We are having problems here with our symantec mail security 4.1. Our queue doesn’t stop increasing and even when mails seem to go trough they’re very slow. It Is not a matter of bandwidth 'cos we have an E1 connection. The problem is when we telnet xxxxx 25 (from inside and outside) it takes up to 10 minutes to get an answer and send the HELO.
Of course this is making us loose tons of mails. Our server is a 2 processors 3.0 GHz with 2GB RAM server which should be enough for 500 people.
I'll appreciate any suggest
