Hi guys
I have been using exim4 for many years and there are some things that I have
never managed to get my head around
I am coming for help and I know many will say I should read the docs but
that is part of the problem. I don't understand!
I am running Exim on an Ubuntu server which I know differs in a number of
ways to the standard configuration and I think may not be supported by this
mailing list but any help will be appreciated
My main issue is with trying to get ACLs working properly
The things I want to do is
When a connection comes from an authenticated client then just let it
proceed
If a connection comes from elsewhere I want it to do fns checking and also
prevent mail being sent as if from me
acl_check_mail:
....
# if you want relaying from friends
accept hosts = +relay_from_hosts
accept authenticated = *
drop condition = whatevercheck you want to fail for a drop
log_message = whatevercheck i like failed for
$sender_address
drop ... next check
...
# Accept all that made it throu the checks
accept
One of my biggest spam problems is with mail appearing as if it is from me,
I am sure this must be easy to filter but I just can't seem to get the
server to even act on filters I try to configure.
:)
put something like this into the above ACL before the final accept
drop condition = ${if
eq{$sender_address}{${local_part}@${domain}}{1}{0}}
log_message = I don't send to myself ...
glad to help out.
Marius
