     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).
     11When 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).
    1212
    1313This is useful to keep up-to-date on an issue or enhancement request that interests you.
    1414
     15=== How to use your username to receive notification mails ===
     16
     17To 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.
     18
     19Alternatively, 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.
     20
     21When 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`''').
     22
    1523== Configuring SMTP Notification ==
    1624
     25'''Important:''' For TracNotification to work correctly, the `[trac] base_url` option must be set in [wiki:TracIni trac.ini].
     26
    1727=== Configuration Options ===
    18 These are the available options for the ''[notification]'' section in trac.ini.
    19  * '''smtp_enabled''': Enable email notification.
    20  * '''smtp_server''': SMTP server used for notification messages.
    21  * '''smtp_port''': (''since 0.9'') Port used to contact the SMTP server.
    22  * '''smtp_user''': (''since 0.9'') User name for authentication SMTP account.
    23  * '''smtp_password''': (''since 0.9'') Password for authentication SMTP account.
    24  * '''smtp_from''': Email address to use for ''Sender''-headers in notification emails.
    25  * '''smtp_from_name''': Sender name to use for ''Sender''-headers in notification emails.
    26  * '''smtp_replyto''': Email address to use for ''Reply-To''-headers in notification emails.
    27  * '''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.
    28  * '''smtp_always_cc''': List of email addresses to always send notifications to. ''Typically used to post ticket changes to a dedicated mailing list.''
    29  * '''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
    30  * '''smtp_subject_prefix''': (''since 0.10.1'') Text that is inserted before the subject of the email. Set to "!__default!__" by default.
    31  * '''always_notify_reporter''':  Always send notifications to any address in the reporter field (default: false).
    32  * '''always_notify_owner''': (''since 0.9'') Always send notifications to the address in the owner field (default: false).
    33  * '''always_notify_updater''': (''since 0.10'') Always send a notification to the updater of a ticket (default: true).
    34  * '''use_public_cc''': (''since 0.10'') Addresses in To: (owner, reporter) and Cc: lists are visible by all recipients (default is ''Bcc:'' - hidden copy).
    35  * '''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.
    36  * '''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.
    37  * '''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:
    38    * `base64`: default value, works with any kind of content. May cause some issues with touchy anti-spam/anti-virus engines.
    39    * `qp` or `quoted-printable`: best for european languages (more compact than base64), not recommended for non-ASCII text (less compact than base64)
    40    * `none`: no encoding. Use with plain english only (ASCII). E-mails with non-ASCII chars won't be delivered.
    41 
    42 Either '''smtp_from''' or '''smtp_replyto''' (or both) ''must'' be set, otherwise Trac refuses to send notification mails.
    43 
    44 === Example Configuration ===

     32 * '''`smtp_from_name`''': Sender name to use for ''Sender''-headers in notification emails.
     33 * '''`smtp_from_author`''': (''since 1.0'') Use the author of a change (the reporter of a new ticket, or the author of a comment) as the `From:` header value in notification e-mails (default: false). If the author hasn't set an e-mail address, `smtp_from` and `smtp_from_name` are used instead.

     49 * '''`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.
     50 * '''`email_sender`''': (''since 0.12'') Name of the component implementing `IEmailSender`. This component is used by the notification system to send emails. Trac currently provides the following components:
     51   * `SmtpEmailSender`: connects to an SMTP server (default).
     52   * `SendmailEmailSender`: runs a `sendmail`-compatible executable.
     53
     54Either '''`smtp_from`''' or '''`smtp_replyto`''' (or both) ''must'' be set, otherwise Trac refuses to send notification mails.
     55
     56The following options are specific to email delivery through SMTP.
     57 * '''`smtp_server`''': SMTP server used for notification messages.
     58 * '''`smtp_port`''': (''since 0.9'') Port used to contact the SMTP server.

     84smtp_always_cc = ticketmaster@example.com, theboss+myproj@example.com
     85}}}
     86
     87=== Customizing the e-mail subject ===
     88The 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:
     89{{{
     90$prefix #$ticket.id: $summary
     91}}}
     92The following variables are available in the template:
     93
     94 * `env`: The project environment (see [trac:source:/trunk/trac/env.py env.py]).
     95 * `prefix`: The prefix defined in `smtp_subject_prefix`.
     96 * `summary`: The ticket summary, with the old value if the summary was edited.
     97 * `ticket`: The ticket model object (see [trac:source:/trunk/trac/ticket/model.py model.py]). Individual ticket fields can be addressed by appending the field name separated by a dot, e.g. `$ticket.milestone`.
     98
     99=== Customizing the e-mail content ===
     100
     101The notification e-mail content is generated based on `ticket_notify_email.txt` in `trac/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:
     102
     103{{{
     104$ticket_body_hdr
     105$ticket_props
     106{% choose ticket.new %}\
     107{%   when True %}\

     163
     164== Customizing e-mail content for MS Outlook ==
     165
     166Out-of-the-box, MS Outlook normally presents plain text e-mails with a variable-width font; 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].
     167
     168Replace the following second row in the template:
     169{{{
     170$ticket_props
     171}}}
     172
     173with this instead (''requires Python 2.6 or later''):
     174{{{
     175--------------------------------------------------------------------------
     176{% with
     177   pv = [(a[0].strip(), a[1].strip()) for a in [b.split(':') for b in
     178         [c.strip() for c in
     179          ticket_props.replace('|', '\n').splitlines()[1:-1]] if ':' in b]];
     180   sel = ['Reporter', 'Owner', 'Type', 'Status', 'Priority', 'Milestone',
     181          'Component', 'Severity', 'Resolution', 'Keywords'] %}\
     182${'\n'.join('%s\t%s' % (format(p[0]+':', ' <12'), p[1]) for p in pv if p[0] in sel)}
     183{% end %}\
     184--------------------------------------------------------------------------
     185}}}
     186
     187The 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.

     223**Important**: Only those ticket fields that are listed in `sel` are part of the HTML mail. If you have defined custom ticket fields which shall be part of the mail they have to be added to `sel`, example:
     224{{{
     225   sel = ['Reporter', ..., 'Keywords', 'Custom1', 'Custom2']
     226}}}
     227
     228However, it's not as perfect as an automatically HTML-formatted e-mail would be, but presented ticket properties are at least readable by default in MS Outlook...
