I was wrong about the problem being intermittent.
. Mail arriving at server1 gets scanned for spam if the
user has requested it. If it is found to be spam, it
is dumped in a per-user spambucket on server1 if the
user has requested it, otherwise it is just discarded.
. Almost all users' mail arriving at server1, which
survives any per-user spam check, is then
forwarded on to another host (alf1 at present)
except for user pdh.
. pdh has accounts on server1 and alf1. webmaster is aliased
to pdh@server1 and postmaster is aliased to pdh@alf1.
. The problem only occurs when mail for pdh or webmaster (which
would have been delivered to his account on server1), fails the
spam check and gets dumped into his spam bucket, but it
*always* occurs under these conditions.
Mail to postmaster which fails the spam check
gets dumped into pdh's spam bucket with no problem.
This is why I thought the problem was intermittent.
Its as if the expansion of $local_part in the spam_transport
(below) is not happening correctly for spam-mail aimed at the
local machine (server1).
Cheers,
Terry.
