[Mailman-Users] Mailman Changing real_name Variable in welcome message subject !

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.


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.
