Mailing-List seems to be ignored an upstream-bugtracker says my mailaddress is invalid - I Have to migrate 10.000 accounts with 90% forwarders in the next days/weeks :-(

http://www.nabble.com/dbmail-forward-seems-to-damage-multimime-messages-td24988293.html

Hy, i trie to explain the problem as good as i can:
Only multi-mime-messages are affected

Here two sample-mails which the same mta-hops, finally both are relayed to
"root@..." which finally points to me. Directly to this address dbmail
is not involved and the mail would not be changed. Both are the same html-mail with the
simple line ".TEST" as multi-mime-message -> Look at the "..TEST" in the second one
Received: by mail.thelounge.net (Postfix, from userid 493) -> 493 = dbmail on fedora

If we send to "transport@..." postfix relays to dbmail-lmtp, dbmail looks in the
alias-table and forwards to "root@...", in this step the leading dot is
added. I think this happens while forwarding because final destination is for both ways
dbmail-lmtp and my inbox

This are two sample-mail-routings to find out what kills our html-mails from mailman
running on "thx1138.thelounge.net" which is an lan-only-maching targeted only with
forward-adress from the mainserver
