[Mailman-Users] Bounce emails and Qmail

[Mike Manning]

Hi there,

We use Mailman 2.1 with Qmail and Plesk (v10.2). Everything works nicely 
with Mailman however it's not sending out the bounce emails to the owner 
to say there are pending requests. Upon checking the 
/var/log/mailman/smtp-failure logs, it's showing that 
website-owner at website.name doesn't exist when mailman tries to send the 
bounce request to the list owner. It does however send back the user who 
sent the email a pending request saying that their email is awaiting 
authorization. There's all the .qmail files in 
/var/qmail/mailnames/website/.qmail-listname-* and have this type of format:

|/var/qmail/bin/preline /usr/lib/plesk-9.0/mm_wrapper 
/usr/lib/mailman/mail/mailman owner websitename

If I try and send an email directly to website-owner at website.name, it'll 
bounce back straight away with:
550 sorry, no mailbox here by that name. (#5.7.17)

It's like qmail isn't passing control to mailman when doing recipient 
verification? Has anyone else had these issues with Plesk and Qmail?

Cheers, Mike
