I have sendmail and popa3d up and running. Is there any way a person could offer mail service to people on ISPs that block port 25 outbound from their networks? I have seen solutions that use different ports, but I'm not sure about doing this with what I have setup on FreeBSD. It seems like you would just have to monitor port 25 and a predetermined port at the same time, and then configure mail clients on the blocked network to send to the predetermined port instead of port 25. I bet everyone starting to block port 25 outside of their own networks really put the hurt on people offering POP3 accounts. I know I can't send e-mail from my own mail server or the POP3 accounts that I pay money for, from my house because of this. I have to use google's POP3 service because it uses different ports for smtp.
