[Mailman-Users] changing the Welcome message on a per list basis... a shot in the dark

Okay, here is the deal...

 - You can simply change the text in subscribeack.txt and you are done.
This changes every welcome message from every list, or

 - You can edit the file ~mailman/Mailman/Deliverer.py and change the
following block of text so that it will check for an existence of an
alternative file to 'subscribeack.txt':
        # get the text from the template
        text = Utils.maketext(
            {'real_name'   : self.real_name,
             'host_name'   : self.host_name,
             'welcome'     : welcome,
             'emailaddr'   : self.GetListEmail(),
             'listinfo_url': self.GetScriptURL('listinfo', absolute=1),
             'optionsurl'  : self.GetOptionsURL(name, absolute=1),
             'password'    : password,

The following function added to Deliverer.py may help..."
def specwelcome(listname):
    """Return special welcome file for `listname' if it exists."""
    # If a special subscibeack.txt file exists in the lists home directory
    # use that instead of the normal one specified in the templates dir
welcfile = os.path.join(mm_cfg.LIST_DATA_DIR, listname, 'subscribeack.txt')
if not os.path.exists(welcfile):
     welcfile = "subscribeack.txt"
return welcfile

This function looks for a copy of the subscribeack.txt file in the lists
home directory (~mailman/lists/<listname>/..).  If it finds a copy then it
uses that, instead of the common one in ~mailman/templates/...
At least, that is what it's supposed to do!

To use it, you would add the function to Deliverer.py and then replace the
existing line (in Deliverer.py):
with something like:


I'm just hacking code together, so this may or may not hose you.  Still its
a start.  Don't be afraid to play with it and get it working just the way
you want!  Python is extremely readable code (unlike perl!).  Remember to
backup any file before you modify it!
