[Mailman-Developers] Problems getting news/mail gateway working (with fixes)

[Steve Phillips]

System:  Debian:  2.0
         Mailman: 1.0b6 (compiled, not from .deb package)
         Inn:     1.7.2 (debian package version 1.7.2-4)

I found one bug in the Python source and one installation error:


I'm trying to set up Mailman on my system to gateway between mail and
news.  I found I was getting the following error in my syslog when
trying to gateway mail to news:

Looks like it failed because the header that innd got was bad.
Investigation revealed this bit of code from GatewayManager.py:


          subj = msg.getheader('subject')
          if not subj:
            msg.SetHeader('Subject', '%s(no subject)' % prefix)
          if self.reply_goes_to_list:
            del msg['reply-to']
            msg.headers.append('Reply-To: %s\n' % self.GetListEmail())
          msg.headers.append('Sender: %s\n' % self.GetAdminEmail())
          msg.headers.append('Errors-To: %s\n' % self.GetAdminEmail())
          msg.headers.append('X-BeenThere: %s\n' % self.GetListEmail())
          msg.headers.append('Newsgroups: %s\n' % self.linked_newsgroup)


Looks like a new Sender: line is getting added, but the original one
is not removed.  I commented out this line and then things started
working.



As for news to mail:

I got the following error for that:

Installed permisions on "post" were:

-rw-r--r--   1 root     mailman      2832 Dec 23 14:14 post


I did chmod 755 on post and then things started working correctly.
