FAQ
Hi all,

I am looking a way in order to change the subject of the welcome message.
In the file in [Mailman home directory/Mailman/Deliverer.py] (line 79) there
is a line :
_('Welcome to the "%(realname)s" mailing list%(digmode)s')

Is there anyway of subtituting the variable realname for one in the
acceptable aliases list (the firts one for instance)?
Is there any variable acceptable_aliases (confs/list.conf) accessable in the
Deliverer.py ?

The objective here is that the list address alias is in the subject line
instead of the list realname.

Any hint is appreciated

best regards to you all

    You could do this in several ways. If you really want to do exactly
    what you said, you could change

    realname = self.real_name
    msg = Message.UserNotification(
    self.GetMemberAdminEmail(name), self.GetRequestEmail(),
    _('Welcome to the "%(realname)s" mailing list%(digmode)s'),
    text, pluser)

    to

    realname = self.acceptable_aliases[0]
    msg = Message.UserNotification(
    self.GetMemberAdminEmail(name), self.GetRequestEmail(),
    _('Welcome to the "%(realname)s" mailing list%(digmode)s'),
    text, pluser)

    but then you have to guarantee that every list has at least one entry
    in acceptable_aliases, because referencing self.acceptable_aliases[0]
    will throw an IndexError exception if the acceptable_aliases list is
    empty.

    A more realistic approach would just be to use the normal list posting
    address, not an alias. Then the code would be

    realname = self.getListAddress()
    msg = Message.UserNotification(
    self.GetMemberAdminEmail(name), self.GetRequestEmail(),
    _('Welcome to the "%(realname)s" mailing list%(digmode)s'),
    text, pluser)

    Note that both of the above change only the first line - the assignment
    to realname.

    If you really wanted to get fancy and use an alias iff there was one,
    you could do

    if self.acceptable_aliases:
    realname = self.acceptable_aliases[0]
    else:
    realname = self.getListAddress()
    msg = Message.UserNotification(
    self.GetMemberAdminEmail(name), self.GetRequestEmail(),
    _('Welcome to the "%(realname)s" mailing list%(digmode)s'),
    text, pluser)

    Cool Mark,

    I followed your directions and it makes all sense, but it appears on the
    subject 2 little squares instead of the acceptable alias that is specified
    in the conf file :P
    I checked the list.conf in conf Directory and acceptable_aliases is
    something like : acceptable_aliases = 'test at test.pt'

    The other variable that you pointed (self.getListAddress()) also gives me
    the list realname.
    Do you have any clue what those 2 little squares instead of the list alias
    name is ?
    To be more specific the subject appears like: Welcome to the mailing list
    "[][]"
    (the brackets are squares ;) )

    Thanks once again mark on your efforts

    Best regards

    Not exactly. It shoud give 'real_name at host_name' instead of just
    'real_name'.

    I thought you perhaps wanted a list email address as opposed to just a
    name which is why I suggested that.

    Do you have any clue what those 2 little squares instead of the list alias
    name is ?
    To be more specific the subject appears like: Welcome to the mailing list
    "[][]"
    (the brackets are squares ;) )

    The squares may represent non-printing characters which may be an issue
    if the acceptable_aliases field begins with a blank line.

    This is partially my error. I was thinking that acceptable_aliases is a
    list, but it is not. It is a string. The construct
    acceptable_alaises[0] returns the first character of the string, which
    if acceptable_aliases = 'test at test.pt', is simply 't', so I don't know
    what the two 'squares' are unless acceptable_aliases begins with a
    blank line, in which case they are probably some representation of a
    carriage-return character.

    So now I have another question. If you don't want people to see the
    name of the list in the subject of the welcome message, why don't you
    just change the list name - see
    <http://www.python.org/cgi-bin/faqw-mm.py?req=show&file=faq04.070.htp>.

    If you really want to keep the list name as is and put the first entry
    from acceptable aliases in the welcome subject, this should do it.

    list_aliases = [alias.strip() for alias in
    self.acceptable_aliases.split()]
    realname = None
    for realname in list_aliases:
    if realname:
    break
    if not realname:
    realname = self.real_name
    msg = Message.UserNotification(
    self.GetMemberAdminEmail(name), self.GetRequestEmail(),
    _('Welcome to the "%(realname)s" mailing list%(digmode)s'),
    text, pluser)

    That will use the first non-empty line from acceptable_aliases if any
    and the list's real_name if there is no non-empty acceptable_aliases
    line.
