Hi,
although I thought my exim config is ok (i read the book (it's always
under my pillow :-D) and the mailing list ), i was a mail relay last
night :-(
The problem is: I don't know why. Perhaps you can give me a hint.
The logfile section of one mail which looks quite normal except the
A=cram authenticator:
2010-12-03 23:11:36 1POdqq-0005Dd-Lg <= notmyloca...@notmydomain1

So, i checked the cram config and I think it's incomplete. I totally
oversee this :-( It seems to allow everything, i comment it out for now.
So how has it to be correct for cram auth? Whats the thing with server
and client config?
cram:
driver = cram_md5
public_name = CRAM-MD5
server_secret = ${lookup pgsql{PG_Q_AUTH_CRAMMD5}}
server_set_id = $auth1
Here is my current acl. Perhaps it is somewhere broken, too.
Thank you
Alexander
