Small Business Server 2003 with Exchange Server 2003 SP2
I've just de-installed Etrust Secure Content Manager from a server that also had Exchange 2003 on it as well. It was set so that Etrust caught mail on port 25 and then forwarded it to Exchange server on port 2525. Everything worked fine like that.
However, the company was being hit by some 500 spam messages per hour, so we decided to use an internet based filtering company to stop the spam before it hit the server.
Anyhow, yesterday I removed Etrust and changed the SMTP virtual server to listen again on port 25 - however, all mail at the internet site is being held due to the Exchange Server not being available.
I've tried to telnet to port 25 and don't get the normal response - just a blinking cursor with no txt reply.
Can anyone suggest what I need to do to make it work again without Etrust.
The IP address hasn't changed, so the firewall port forwarding is still the same - I've also tried setting the server as a DMZ - but still get no response.
Also looked at the services file and there are no changes or additions to SMTP on port 25.
Please help this is extremly urgent.
Thanks and Regards
