[Bug 544477] [NEW] setting localhost in postfix_lmtp breaks delivery

[Patrick Ben Koetter]

Public bug reported:

Setting localhost in postfix_lmtp works against Postfix defaults and
breaks delivery.

Reason: The Postfix lmtp client only uses dns queries by default to
search for hostnames. If the DNS server does not provide an answer for
"localhost" delivery from the lmtp client to mailman fails.

Solution: Provide "127.0.0.1" instead of "localhost". This does not
require DNS and is even faster because it saves DNS lookups.

Example:

hey2 at mailman.state-of-mind.de
lmtp:[localhost.localdomain]:8024

** Affects: mailman
