I'm trying to figure out the best way to battle the problems that certain ISP's are causing our customers by blocking port 25. I'm currently thinking of mapping port 2525 through our firewall to point to port 25 on the internal interface.
Actually, you'll want to map port 587 (which RFC2476 designates for MTAs sending E-mail) to port 25.
My question is, rather than having to reconfigure each static mapping in our firewall, is it possible to have users send their login to [EMAIL PROTECTED], and have them send mail using a different mail server? We're considering creating a relay1.host.com so that we can just send the same instructions to all of our clients. This is also how we can create a host for each of our imail servers. We currently have 4 servers&
I'm not sure what you are trying to accomplish here? If you set up your firewall to map port 587 to port 25 (both on the IP of the mailserver), you're all set. People can then send mail, without having to use another mailserver (which won't work unless it, too, has port 587 mapped to it, so it would just add an extra unnecessary step).
By only using the one server, users only have to switch their mail client to send to port 587. They won't need to also change the hostname they connect to.
