Topic: Accepting port 110 traffic from only one ip

you can have 2 servers listening on 25 at the same time with the same address..

I think you mean "can't".

I use the SME server as spamfilter infront of an Exchange server and it catches close to all spam and marks all the rest perfectly (moved to "Exchange Junk E-mail folder")

maybe the spammers are getting smarter but I find that the filter doesn't catch anywhere near as much as it used to, a lot seems to slip by, emails sent by people using Foxmail (very popular email client used in China) more often than not end up in the junkmail folder also, I know there is a compliance issue with Foxmail (other mail servers seem to pass their mail ok though) but it's hard to try and re-educate so many users and get them to use something different

jookin,

Surely they are getting smarter - all the time. Tuning the spamfilter is a continuous job I am afraid. What I have done with success is to:

1) Enable DCC (/etc/mail/spamassassin/v310.pre)
2) Utilize the unofficial clamav signatures (http://wiki.contribs.org/Email#Anti_Virus)
3) reject emails with score above 9 and tags above 5
4) install the server-manager module that allows whitelistning - sometimes its needed

If there are certain SA rules that creates the false positives then you might want to increase their score.
