Hi all,
I use exim for quite some time in our office, but some users are unhappy with
our spam filtering, because they think they loose important mails. Currently we
just drop all spam-assassin classified mail in the ACL, like:
deny message = Our software thinks the message was spam
spam = nobody
To make those users more happy I wanted to change the exim configuration to
instead move the classified messages in an spam sub-folder so they can review
if they think they missed something. However, after some hours of trial'n error
I have not found a perfect solution. The best so far was to mark the message
header and use the system filter like:
if $h_X-Spam-IsSpam contains "1" and not error_message
then
save $home/Maildir/.0-Spam/
fail text "The message was classified as SPAM and might not be seen by
a human user ..."
endif
However, this has multiple drawbacks: First the message is initially accepted,
and thus we might continue receiving spam thru this channel (host) as it thinks
the address is valid and continues sending, and second, the filter "fail"
action will often generate a new message directly to the user as much spam is
send with From: == To: so that the new fail error message get's to the user
which did not send it, ...
I'm wondering if there is something like "deny but continue" in the ACL config
that would indicate an error in the "data-in receive phase" and thus let the
upstream host generate the error message, if any, but continue delivering the
message locally so that exim can save it into some "potentially spam"
sub-directory.
Thanks in advance,
René
