So I have just installed SMTP on my 2008 R2 server. The pickup works great, that's fine.. however the drop section is having no avail - nothing is coming in.
I have both ports 25 & 110 open on my firewall, host records setup for mail.domain.com as well as the mx record.
If I email from within the server (locally) it works, but not from outside of the server.
Does anybody spot an issue with my setup here?
Thanks!
