I wanted to build an awesome place for people to discuss module specific issues, but I don't have any more time for this, and there are much better places to discuss Perl-related issues. I'd recommend asking your question on Stack Overflow or on Perl Monks.
If you are looking for a Perl tutorial or Perl-related news, I hope these links will serve you well.
Mail-DKIM

Is there anyway to handle email signed with DKIM going through a list server?
Appreciate your advice how to deal with emails that signed with DKIM sending to an external list whereby some of the members in this lists are our users. When an email sent through the list server, it will somehow be tempered, is there anyway to deal with this issue so that our users are able to receive the message? Thank you.

Yes, this is true. The original signature will no longer be valid.

Ideally the mailing list itself will add its own signature, and the receiver will use the mailing list signature when determining the disposition of the message.

That depends on why your users are unable to receive the message? Are you preventing delivery on messages that are missing a DKIM signature? As you can see, that is probably not a good idea. At the least, it should only be done for messages claiming to be from a domain that always signs its mail and never sends mail through a mailing list that alters messages.
