hi

we are running a webserver win 2000/IIS together with the mercur mailserver (www.atrium.de).
even if we have the imprssion that we configured the mailserver to be quite safe
we have the impression that it is being misused by spammers :-(

is there any way to "monitoring" all outgoing mail in a convinient way to figure out if the mailserver is used by not authorized users. some sort of tool where we could see all outgoing mail listed in a handy way. this because reading the mailserver protocol is a bit of a hazzle...

any hints, especially on the mercur mail server are very much appreciated.

thank you in advance / joergen astroem

i noticed that mercur mail server has built-in anti-spamming feature for outgoing messages, you may even can specify the following protection mechanisms to customize your solution:

1. Check name of sending host
2. Reject mail, if originator domain has no MX record
3. Do not relay, if the originator address is not local
4. Do not relay, if the originator domain is not local
5. Reject incoming mail, if number of external recipients exceeds
6. Info to administrator, if number of external recipients exceeds

for more information how about how to configure it step-by-step, see page 110 of "MERCUR Mailserver Version 4 Usermanual", download at: http://www.atrium-softwareusa.com/EN/manuals/mcrmanualpdfen.zip

if you have any further questions, please let us know.

hope it helps,
