    33
    44Trac supports notification of ticket changes via email.
    55
    6 Email 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.
    7 
    8 Disabled by default, notification can be activated and configured in [wiki:TracIni trac.ini].

     10== Receiving Notification Mails
    1111When 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.
    1212
    13 === How to use your username to receive notification mails ===
    14 
    15 To 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.
     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 your [/prefs preferences].
    1616
    1717Alternatively, 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.

    31 '''Important:''' For TracNotification to work correctly, the `[trac] base_url` option must be set in [wiki:TracIni trac.ini].

     31'''Important:''' The [[TracIni#trac-base_url-option|[trac] base_url]] option must be configured for links in the notification message to be correctly generated.

     33=== Configuration Options
    3434These are the available options for the `[notification]` section in trac.ini:

    5858
    59 === Customizing the e-mail subject ===
     59=== Subscriber Configuration
     60The default subscriptions are configured in the [TracIni#notification-subscriber-section "[notification-subscriber]"] section.
     61
     62[[TracIni(section=notification-subscriber)]]
     63
     64Each user can override these defaults in their ''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
     68The subscription rule name on the left side of the `=` can be anything, it has no meaning outside this configuration file. The subscriber name on the right side of the `=` must be one of the subscribers listed in the above table.
     69
     70The following attributes of default subscriptions can be configured:
     71* `.distributor` (Default: `email`)
     72  * Other values require plugins. For example `on-site` requires th:OnSiteNotificationsPlugin.
     73* `.priority` (Default: `100`)
     74  * Smaller values override larger values.
     75  * If you use `0`, then users will not be able to override this rule.
     76* `.adverb` (Default: `always`)
     77  * `never` can be used to silence other subscription rules with higher values.
     78* `.format` (Default: `text/plain`)
     79  * Other values require plugins. For example `text/html` requires th:TracHtmlNotificationPlugin.
     80
     81=== Example Configuration (default subscriptions)
     82{{{#!ini
     83[notification-subscriber]
     84always_notify_owner = TicketOwnerSubscriber
     85always_notify_owner.distributor = email
     86always_notify_owner.priority = 100

     97notify_cc_html.format = text/html
     98}}}
     99
     100=== Customizing the e-mail subject
    60101The 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:
    61 {{{
    62 $prefix #$ticket.id: $summary
     102{{{#!genshi
     103${prefix} #${ticket.id}: ${summary}
    63104}}}
    64105The following variables are available in the template:
    65106
    66  * `env`: The project environment (see [trac:source:/trunk/trac/env.py env.py]).
     107 * `env`: The project environment object (see [trac:source:branches/1.2-stable/trac/env.py env.py]).
    67108 * `prefix`: The prefix defined in `smtp_subject_prefix`.
    68109 * `summary`: The ticket summary, with the old value if the summary was edited.
    69  * `ticket`: The ticket model object (see [trac:source:/trunk/trac/ticket/model.py model.py]). Individual ticket fields can be addressed by appending the field name separated by a dot, eg `$ticket.milestone`.
    70 
    71 === Customizing the e-mail content ===
    72 
    73 The notification e-mail content is generated based on `ticket_notify_email.txt` in `trac/ticket/templates`. You can add your own version of this template by adding a `ticket_notify_email.txt` to the templates directory of your environment. The default looks like this:
    74 
    75 {{{
     110 * `ticket`: The ticket model object (see [trac:source:branches/1.2-stable/trac/ticket/model.py model.py]). Individual ticket fields can be accessed by appending the field name separated by a dot, eg `${ticket.milestone}`.

     112=== Customizing the e-mail content
     113
     114The notification e-mail content is generated based on `ticket_notify_email.txt` in `trac/ticket/templates`. You can add your own version of this template by adding a `ticket_notify_email.txt` to the templates directory of your environment. The default is:

    136 == Customizing e-mail content for MS Outlook ==
    137 
    138 MS 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].
    139 
    140 Replace the following second row in the template:
    141 {{{
    142 $ticket_props
    143 }}}
    144 
    145 with this (requires Python 2.6 or later):
    146 {{{
    147 --------------------------------------------------------------------------
    148 {% with
    149    pv = [(a[0].strip(), a[1].strip()) for a in [b.split(':') for b in
    150          [c.strip() for c in
    151           ticket_props.replace('|', '\n').splitlines()[1:-1]] if ':' in b]];
    152    sel = ['Reporter', 'Owner', 'Type', 'Status', 'Priority', 'Milestone',
    153           'Component', 'Severity', 'Resolution', 'Keywords'] %}\
    154 ${'\n'.join('%s\t%s' % (format(p[0]+':', ' <12'), p[1]) for p in pv if p[0] in sel)}
    155 {% end %}\
    156 --------------------------------------------------------------------------
    157 }}}
    158 
    159 The 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.

    193 }}}
    194 
    195 **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:
    196 {{{
    197    sel = ['Reporter', ..., 'Keywords', 'Custom1', 'Custom2']
    198 }}}
    199 
    200 However, the solution is still a workaround to an automatically HTML-formatted e-mail.
    201 
    202 == Using GMail as the SMTP relay host ==
     179== Using GMail as the SMTP relay host
    203180
    204181Use the following configuration snippet:
    205 {{{
     182{{{#!ini
    206183[notification]
    207184smtp_enabled = true
    … …  
    218195Alternatively, you can use `smtp_port = 25`.[[br]]
    219196You 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.
    220  
    221 == Filtering notifications for one's own changes and comments ==
    222 In Gmail, use the filter:
    223 {{{
    224 from:(<smtp_from>) (("Reporter: <username>" -Changes -Comment) OR "Changes (by <username>)" OR "Comment (by <username>)")
    225 }}}
    226 
    227 to delete these notifications.
    228 
    229 In Thunderbird, there is no such solution if you use IMAP, see http://kb.mozillazine.org/Filters_(Thunderbird)#Filtering_the_message_body.
    230 
    231 You can also add this plugin:
    232 http://trac-hacks.org/wiki/NeverNotifyUpdaterPlugin, or vote for [trac:#2247] to be fixed.
    233 
    234 == Troubleshooting ==
    235 
    236 If 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.
    237 
    238 Notification 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.
    239 
    240 === ''Permission denied'' error ===
     197
     198== Troubleshooting
     199
     200If notifications are not working, inspect the [TracLogging log] for error messages.
     201
     202Notification errors are not always reported through the web interface, so the user who submits a change or creates a ticket may not get notified about a notification failure. The Trac administrator needs to look at the log to find the error message and traceback.
     203
     204=== ''Permission denied'' error
    241205
    242206Typical error message:
    243 {{{
     207{{{#!sh
    244208  ...
    245209  File ".../smtplib.py", line 303, in connect
    … …  
    251215
    252216Many users get confused when their manual attempts to contact the SMTP server succeed:
    253 {{{
     217{{{#!sh
    254218telnet localhost 25
    255219}}}
    256220This is because a regular user may connect to the SMTP server, but the web server cannot:
    257 {{{
     221{{{#!sh
    258222sudo -u www-data telnet localhost 25
    259223}}}
    … …  
    265229
    266230For SELinux in Fedora 10:
    267 {{{
     231{{{#!sh
    268232$ setsebool -P httpd_can_sendmail 1
    269233}}}
    270234
    271 === ''Suspected spam'' error ===
     235=== ''Suspected spam'' error
    272236
    273237Some SMTP servers may reject the notification email sent by Trac.
