Hi,
when using multiple outbound IPs in master.cf and FILTER we encountered an
unfortunate problem.
Postfix seems not to update the nexthop when a filter matches in a
multi-recipient mail.
As you see from the log Postfix tries to deliver each mail to the same MX
(in this case mx-ha01.web.de).
Is this a configuration error or maybe a bug in Postfix?
