I'm trying to configure SMTP using the IMS under Exchange 5.5 SP4, but port 25 on the server is blocked/not listening. I've tried re-starting the IMS, but it still won't open.

have you assigned a mailbox to the IMC properties Internet Mail tab. The IMC wont start until there is a mailbox listed there.

Hope this helps.

I am assuming from what you have said that the IMS is starting correctly??

Are you running IIS on the box? If so, check that there is no Web Page trying to use port 25 on the local server as well.

Also try telnet to the server on port 25 fromanother machine and see what sort of response you get from it.

Regards.
