Description Daniel Faber 2006-05-24 14:11:19 UTC

couriermlm can't deliver mailing list messages to adresses
with an equal sign in the user part.  All versions up to courier-0.53.1 are affected.

Steps to reproduce:

* Create a test mailing list with
  couriermlm create <dir> ADDRESS=<address>
  and create the necessary .courier files

* Subscribe an address with an equal sign
  couriermlm sub <dir> foo=bar@somewhere.org
  and make sure you can receive mail with this address

* Subscribe another address without equal sign for tesing
  couriermlm sub <dir> foo-bar@somewhere.org

* Send a mail to this list

Result:

* foo-bar@somewhere.org receives the message, foo=bar@somewhere.org
  doesn't

* mailq lists the mail for foo=bar@somewhere.org

* top shows a courieresmtp process with 99% cpu usage (we also tried a
  local address with equal sign, in this case it's a courierlocal
  process)

* some minutes later the courierlocal process exits and the log shows
  err courierlocal: Error: stuck delivery, PID 1001, sending signal 15

I reported this bug to the courier-users mailing list and courier's author Sam Varshavchik wrote a patch that fixes it.
