I'm trying to make it easy to manage mailing lists on my server. I have created a user called "list" who managed all lists.

In order to avoid creating 3 .courier files for each list created, I decided to create a single .courier-default file as follows:

||./wrapper

The wrapper script is a little program that looks at the environment variables and prints out the appropriate couriermlm command, which courier is then supposed to execute. For example, if I send email to anand-help@, then the wrapper print out:

|/usr/lib/courier/bin/couriermlm ctlmsg anand

But when I try to run this, I get deferrals with the following log entry:

Jun 27 14:51:08 dali courierlocal:
id=000AE704.3D1B0976.00005192,from=<ana...@celtelplus.com>,addr=<list...@dali.celtelplus.com>:
Invalid address. Jun 27 14:51:08 dali courierlocal:
id=000AE704.3D1B0976.00005192,from=<ana...@celtelplus.com>,addr=<list...@dali.celtelplus.com>,status:
deferred

The wrapper looks like this:

#!/usr/bin/python2.1 import os, string ext = os.environ['EXT'] mlm = '|/usr/lib/courier/bin/couriermlm' sendmail = '|/usr/lib/courier/bin/sendmail' owneraddress = 'post...@celtelplus.com' if os.environ['EXT2'] == 'owner': # dispatch to list owner command = sendmail + ' -f "' + os.environ['SENDER'] + '" ' + owneraddress elif '-' in ext: # dispatch to list controller command = mlm + ' ctlmsg ' + string.split(ext,'-')[0] else: # address has no special actions, so likely a list # dispatch to list command = mlm + ' msg ' + ext print command
