    4 Trac supports notification about ticket changes via email.
     4Trac supports notification of ticket changes via email.
    55
    66Email 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.
     
    99
    1010== Receiving Notification Mails ==
    11 When reporting a new ticket or adding a comment, enter a valid email address 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 This is useful to keep up-to-date on an issue or enhancement request that interests you.
     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}}}
    1428
    1529== Configuring SMTP Notification ==
    1630
     31'''Important:''' For TracNotification to work correctly, the `[trac] base_url` option must be set in [wiki:TracIni trac.ini].
     32
    1733=== Configuration Options ===
    18 These are the available options for the `[notification]` section in trac.ini.
    19 
    20  * '''`smtp_enabled`''': Enable email notification.
    21  * '''`smtp_from`''': Email address to use for ''Sender''-headers in notification emails.
    22  * '''`smtp_from_name`''': Sender name to use for ''Sender''-headers in notification emails.
    23  * '''`smtp_replyto`''': Email address to use for ''Reply-To''-headers in notification emails.
    24  * '''`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.
    25  * '''`smtp_always_cc`''': List of email addresses to always send notifications to. ''Typically used to post ticket changes to a dedicated mailing list.''
    26  * '''`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
    27  * '''`smtp_subject_prefix`''': (''since 0.10.1'') Text that is inserted before the subject of the email. Set to "!__default!__" by default.
    28  * '''`always_notify_reporter`''':  Always send notifications to any address in the reporter field (default: false).
    29  * '''`always_notify_owner`''': (''since 0.9'') Always send notifications to the address in the owner field (default: false).
    30  * '''`always_notify_updater`''': (''since 0.10'') Always send a notification to the updater of a ticket (default: true).
    31  * '''`use_public_cc`''': (''since 0.10'') Addresses in To: (owner, reporter) and Cc: lists are visible by all recipients (default is ''Bcc:'' - hidden copy).
    32  * '''`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.
    33  * '''`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:
    34    * `base64`: default value, works with any kind of content. May cause some issues with touchy anti-spam/anti-virus engines.
    35    * `qp` or `quoted-printable`: best for european languages (more compact than base64), not recommended for non-ASCII text (less compact than base64)
    36    * `none`: no encoding. Use with plain english only (ASCII). E-mails with non-ASCII chars won't be delivered.
    37  * '''`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.
    38 
    39 Either '''`smtp_from`''' or '''`smtp_replyto`''' (or both) ''must'' be set, otherwise Trac refuses to send notification mails.
    40 
    41 The following options are specific to email delivery through SMTP.
    42  * '''`smtp_server`''': SMTP server used for notification messages.
    43  * '''`smtp_port`''': (''since 0.9'') Port used to contact the SMTP server.
    44  * '''`smtp_user`''': (''since 0.9'') User name for authentication SMTP account.
    45  * '''`smtp_password`''': (''since 0.9'') Password for authentication SMTP account.
    46  * '''`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.
    47 
     34These are the available options for the `[notification]` section in trac.ini:

    6059=== Customizing the e-mail subject ===
     
    6867 * `prefix`: The prefix defined in `smtp_subject_prefix`.
    6968 * `summary`: The ticket summary, with the old value if the summary was edited.
    70  * `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. `$ticket.milestone`.
     69 * `ticket`: The ticket model object (see [trac:source:/trunk/trac/ticket/model.py model.py]). Individual ticket fields can be addressed by appending the field name separated by a dot, eg `$ticket.milestone`.
     70
     71=== Customizing the e-mail content ===
     72
     73The 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{{{
     76$ticket_body_hdr
     77$ticket_props
     78{% choose ticket.new %}\
     79{%   when True %}\

     136== Customizing e-mail content for MS Outlook ==
     137
     138MS 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
     140Replace the following second row in the template:
     141{{{
     142$ticket_props
     143}}}
     144
     145with this (requires Python 2.6 or later):
     146{{{
     147--------------------------------------------------------------------------
     148{% with
     149   pv = [(a[0].strip(), a[1].strip()) for a in [b.split(':') for b in
     150         [c.strip() for c in
     151          ticket_props.replace('|', '\n').splitlines()[1:-1]] if ':' in b]];
     152   sel = ['Reporter', 'Owner', 'Type', 'Status', 'Priority', 'Milestone',
     153          'Component', 'Severity', 'Resolution', 'Keywords'] %}\
     154${'\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
     159The 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.

     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
     200However, the solution is still a workaround to an automatically HTML-formatted e-mail.

    113217
    114218Alternatively, you can use `smtp_port = 25`.[[br]]
    115 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.

     221== Filtering notifications for one's own changes and comments ==
    118222In Gmail, use the filter:
    119 
    120 {{{
    121 from:(<smtp_from>) (("Reporter: <username>" -Changes) OR "Changes (by <username>)")
     223{{{
     224from:(<smtp_from>) (("Reporter: <username>" -Changes -Comment) OR "Changes (by <username>)" OR "Comment (by <username>)")
    122225}}}
    123226
    124227to delete these notifications.
    125228
    126 In Thunderbird, there is no such solution if you use IMAP
    127 (see http://kb.mozillazine.org/Filters_(Thunderbird)#Filtering_the_message_body).
    128 
    129 The best you can do is to set "always_notify_updater" in conf/trac.ini to false.
    130 You will however still get an email if you comment a ticket that you own or have reported.
     229In Thunderbird, there is no such solution if you use IMAP, see http://kb.mozillazine.org/Filters_(Thunderbird)#Filtering_the_message_body.
    131230
    132231You can also add this plugin:
    133 http://trac-hacks.org/wiki/NeverNotifyUpdaterPlugin
     232http://trac-hacks.org/wiki/NeverNotifyUpdaterPlugin, or vote for [trac:#2247] to be fixed.
    134233
    135234== Troubleshooting ==
     
    137236If 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.
    138237
    139 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.

    162 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.

    171 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.
    172 
    173 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.
