    5 
    6 Trac supports notification about ticket changes via email.
     4Trac supports notification of ticket changes via email.
    75
    86Email notification is useful to keep users up-to-date on tickets/issues of interest, and also provides a convenient way to post all ticket changes to a dedicated mailing list. For example, this is how the [http://lists.edgewall.com/archive/trac-tickets/ Trac-tickets] mailing list is set up.
     
    108Disabled by default, notification can be activated and configured in [wiki:TracIni trac.ini].
    119
    12 == Receiving Notification Mails ==
    13 When reporting a new ticket or adding a comment, enter a valid email address or your username in the ''reporter'', ''assigned to/owner'' or ''cc'' field. Trac will automatically send you an email when changes are made to the ticket (depending on how notification is configured).
    14 
    15 This is useful to keep up-to-date on an issue or enhancement request that interests you.
    16 
    17 === How to use your username to receive notification mails ===
    18 
    19 To receive notification mails, you can either enter a full email address or your username. To get notified with a simple username or login, you need to specify a valid email address in the ''Preferences'' page.
    20 
    21 Alternatively, a default domain name ('''`smtp_default_domain`''') can be set in the TracIni file (see [#ConfigurationOptions Configuration Options] below). In this case, the default domain will be appended to the username, which can be useful for an "Intranet" kind of installation.
    22 
    23 == Configuring SMTP Notification ==
     10== Receiving Notification Mails
     11When reporting a new ticket or adding a comment, enter a valid email address or your Trac username in the ''reporter'', ''assigned to/owner'' or ''cc'' field. Trac will automatically send you an email when changes are made to the ticket, depending on how notification is configured.
     12
     13=== How to use your username to receive notification mails
     14
     15To receive notification mails, you can either enter a full email address or your Trac username. To get notified with a simple username or login, you need to specify a valid email address in the ''Preferences'' page.
     16
     17Alternatively, a default domain name ('''`smtp_default_domain`''') can be set in the TracIni file, see [#ConfigurationOptions Configuration Options] below. In this case, the default domain will be appended to the username, which can be useful for an "Intranet" kind of installation.
     18
     19When using apache and mod_kerb for authentication against Kerberos / Active Directory, usernames take the form ('''`username@EXAMPLE.LOCAL`'''). To avoid this being interpreted as an email address, add the Kerberos domain to  ('''`ignore_domains`''').
     20
     21=== Ticket attachment notifications
     22
     23Since 1.0.3 Trac will send notifications when a ticket attachment is added or deleted. Usually attachment notifications will be enabled in an environment by default. To disable the attachment notifications for an environment the `TicketAttachmentNotifier` component must be disabled:
     24{{{#!ini
     25[components]
     26trac.ticket.notification.TicketAttachmentNotifier = disabled
     27}}}
     28
     29== Configuring SMTP Notification
    2430
    2531'''Important:''' For TracNotification to work correctly, the `[trac] base_url` option must be set in [wiki:TracIni trac.ini].
    2632
    27 === Configuration Options ===
    28 These are the available options for the `[notification]` section in trac.ini.
    29 
    30  * '''`smtp_enabled`''': Enable email notification.
    31  * '''`smtp_from`''': Email address to use for ''Sender''-headers in notification emails.
    32  * '''`smtp_from_name`''': Sender name to use for ''Sender''-headers in notification emails.
    33  * '''`smtp_replyto`''': Email address to use for ''Reply-To''-headers in notification emails.
    34  * '''`smtp_default_domain`''': (''since 0.10'') Append the specified domain to addresses that do not contain one. Fully qualified addresses are not modified. The default domain is appended to all username/login for which an email address cannot be found from the user settings.
    35  * '''`smtp_always_cc`''': List of email addresses to always send notifications to. ''Typically used to post ticket changes to a dedicated mailing list.''
    36  * '''`smtp_always_bcc`''': (''since 0.10'') List of email addresses to always send notifications to, but keeps addresses not visible from other recipients of the notification email
    37  * '''`smtp_subject_prefix`''': (''since 0.10.1'') Text that is inserted before the subject of the email. Set to "!__default!__" by default.
    38  * '''`always_notify_reporter`''':  Always send notifications to any address in the reporter field (default: false).
    39  * '''`always_notify_owner`''': (''since 0.9'') Always send notifications to the address in the owner field (default: false).
    40  * '''`always_notify_updater`''': (''since 0.10'') Always send a notification to the updater of a ticket (default: true).
    41  * '''`use_public_cc`''': (''since 0.10'') Addresses in To: (owner, reporter) and Cc: lists are visible by all recipients (default is ''Bcc:'' - hidden copy).
    42  * '''`use_short_addr`''': (''since 0.10'') Enable delivery of notifications to addresses that do not contain a domain (i.e. do not end with ''@<domain.com>'').This option is useful for intranets, where the SMTP server can handle local addresses and map the username/login to a local mailbox. See also `smtp_default_domain`. Do not use this option with a public SMTP server.
    43  * '''`mime_encoding`''': (''since 0.10'') E-mail notifications are always sent in 7-bit mode. This option allows to select the MIME encoding scheme. Supported values:
    44    * `base64`: default value, works with any kind of content. May cause some issues with touchy anti-spam/anti-virus engines.
    45    * `qp` or `quoted-printable`: best for european languages (more compact than base64), not recommended for non-ASCII text (less compact than base64)
    46    * `none`: no encoding. Use with plain english only (ASCII). E-mails with non-ASCII chars won't be delivered.
    47  * '''`ticket_subject_template`''': (''since 0.11'') A [http://genshi.edgewall.org/wiki/Documentation/text-templates.html Genshi text template] snippet used to get the notification subject.
    48 
    49 Either '''`smtp_from`''' or '''`smtp_replyto`''' (or both) ''must'' be set, otherwise Trac refuses to send notification mails.
    50 
    51 The following options are specific to email delivery through SMTP.
    52  * '''`smtp_server`''': SMTP server used for notification messages.
    53  * '''`smtp_port`''': (''since 0.9'') Port used to contact the SMTP server.
    54  * '''`smtp_user`''': (''since 0.9'') User name for authentication SMTP account.
    55  * '''`smtp_password`''': (''since 0.9'') Password for authentication SMTP account.
    56  * '''`use_tls`''': (''since 0.10'') Toggle to send notifications via a SMTP server using [http://en.wikipedia.org/wiki/Transport_Layer_Security TLS], such as GMail.

     56smtp_always_cc = ticketmaster@example.com, theboss+myproj@example.com
     57}}}
     58
     59=== Subscriber Configuration
     60The default subscriptions are configured in the `[notification-subscriber]` section in trac.ini:
     61
     62[[TracIni(notification-subscriber)]]
     63
     64Each user can override these defaults in his ''Notifications'' preferences.
     65
     66For example to unsubscribe from notifications for one's own changes and comments, the rule "Never notify: I update a ticket" should be added above other subscription rules.
     67
     68=== Customizing the e-mail subject
    7169The e-mail subject can be customized with the `ticket_subject_template` option, which contains a [http://genshi.edgewall.org/wiki/Documentation/text-templates.html Genshi text template] snippet. The default value is:
    72 {{{
     70{{{#!genshi
    7371$prefix #$ticket.id: $summary
    7472}}}
     
    7876 * `prefix`: The prefix defined in `smtp_subject_prefix`.
    7977 * `summary`: The ticket summary, with the old value if the summary was edited.
    80  * `ticket`: The ticket model object (see [trac:source:/trunk/trac/ticket/model.py model.py]). Individual ticket fields can be addressed by appending the field name separated by a dot, e.g. `$ticket.milestone`.
    81 
    82 === Customizing the e-mail content ===
    83 
    84 The notification e-mail content is generated based on `ticket_notify_email.txt` in `trac/ticket/templates`. The default looks like this:
    85 
    86 {{{
     78 * `ticket`: The ticket model object (see [trac:source:/trunk/trac/ticket/model.py model.py]). Individual ticket fields can be addressed by appending the field name separated by a dot, eg `$ticket.milestone`.

     145== Customizing e-mail content for MS Outlook
     146
     147MS Outlook normally presents plain text e-mails with a variable-width font, and as a result the ticket properties table will most certainly look like a mess in MS Outlook. This can be fixed with some customization of the [#Customizingthee-mailcontent e-mail template].
     148
     149Replace the following second row in the template:
     150{{{
     151$ticket_props
     152}}}
     153
     154with this (requires Python 2.6 or later):
     155{{{
     156--------------------------------------------------------------------------
     157{% with
     158   pv = [(a[0].strip(), a[1].strip()) for a in [b.split(':') for b in
     159         [c.strip() for c in
     160          ticket_props.replace('|', '\n').splitlines()[1:-1]] if ':' in b]];
     161   sel = ['Reporter', 'Owner', 'Type', 'Status', 'Priority', 'Milestone',
     162          'Component', 'Severity', 'Resolution', 'Keywords'] %}\
     163${'\n'.join('%s\t%s' % (format(p[0]+':', ' <12'), p[1]) for p in pv if p[0] in sel)}
     164{% end %}\
     165--------------------------------------------------------------------------
     166}}}
     167
     168The table of ticket properties is replaced with a list of a selection of the properties. A tab character separates the name and value in such a way that most people should find this more pleasing than the default table when using MS Outlook.

     203
     204**Important**: Only those ticket fields that are listed in `sel` are part of the HTML mail. If you have defined custom ticket fields which are to be part of the mail, then they have to be added to `sel`. Example:
     205{{{
     206   sel = ['Reporter', ..., 'Keywords', 'Custom1', 'Custom2']
     207}}}
     208
     209However, the solution is still a workaround to an automatically HTML-formatted e-mail.
     210
     211== Using GMail as the SMTP relay host
     212
     213Use the following configuration snippet:
     214{{{#!ini
    150215[notification]
    151216smtp_enabled = true
     
    158223}}}
    159224
    160 where ''user'' and ''password'' match an existing GMail account, ''i.e.'' the ones you use to log in on [http://gmail.com]
     225where ''user'' and ''password'' match an existing GMail account, ie the ones you use to log in on [http://gmail.com].
    161226
    162227Alternatively, you can use `smtp_port = 25`.[[br]]
    163 You should not use `smtp_port = 465`. It will not work and your ticket submission may deadlock. Port 465 is reserved for the SMTPS protocol, which is not supported by Trac. See [comment:ticket:7107:2 #7107] for details.
    164  
    165 == Filtering notifications for one's own changes ==
    166 In Gmail, use the filter:
    167 
    168 {{{
    169 from:(<smtp_from>) (("Reporter: <username>" -Changes) OR "Changes (by <username>)")
    170 }}}
    171 
    172 For Trac .10, use the filter:
    173 {{{
    174 from:(<smtp_from>) (("Reporter: <username>" -Changes -Comment) OR "Changes (by <username>)" OR "Comment (by <username>)")
    175 }}}
    176 
    177 to delete these notifications.
    178 
    179 In Thunderbird, there is no such solution if you use IMAP
    180 (see http://kb.mozillazine.org/Filters_(Thunderbird)#Filtering_the_message_body).
    181 
    182 The best you can do is to set "always_notify_updater" in conf/trac.ini to false.
    183 You will however still get an email if you comment a ticket that you own or have reported.
    184 
    185 You can also add this plugin:
    186 http://trac-hacks.org/wiki/NeverNotifyUpdaterPlugin
    187 
    188 == Troubleshooting ==
     228You should not use `smtp_port = 465`. Doing so may deadlock your ticket submission. Port 465 is reserved for the SMTPS protocol, which is not supported by Trac. See [trac:comment:2:ticket:7107 #7107] for details.
     229
     230== Troubleshooting
    189231
    190232If you cannot get the notification working, first make sure the log is activated and have a look at the log to find if an error message has been logged. See TracLogging for help about the log feature.
    191233
    192 Notification errors are not reported through the web interface, so the user who submit a change or a new ticket never gets notified about a notification failure. The Trac administrator needs to look at the log to find the error trace.

    194 === ''Permission denied'' error ===
     234Notification errors are not reported through the web interface, so the user who submits a change or a new ticket never gets notified about a notification failure. The Trac administrator needs to look at the log to find the error trace.

    203245
    204 This error usually comes from a security settings on the server: many Linux distributions do not let the web server (Apache, ...) to post email message to the local SMTP server.

     249{{{#!sh

    213255}}}
    214256
    215 In such a case, you need to configure your server so that the web server is authorized to post to the SMTP server. The actual settings depend on your Linux distribution and current security policy. You may find help browsing the Trac [trac:MailingList MailingList] archive.

     267=== ''Suspected spam'' error
    225268
    226269Some SMTP servers may reject the notification email sent by Trac.
    227270
    228 The default Trac configuration uses Base64 encoding to send emails to the recipients. The whole body of the email is encoded, which sometimes trigger ''false positive'' SPAM detection on sensitive email servers. In such an event, it is recommended to change the default encoding to "quoted-printable" using the `mime_encoding` option.
    229 
    230 Quoted printable encoding works better with languages that use one of the Latin charsets. For Asian charsets, it is recommended to stick with the Base64 encoding.
    231 
    232 === ''501, 5.5.4 Invalid Address'' error ===

     271The default Trac configuration uses Base64 encoding to send emails to the recipients. The whole body of the email is encoded, which sometimes trigger ''false positive'' spam detection on sensitive email servers. In such an event, change the default encoding to "quoted-printable" using the `mime_encoding` option.
