    Overall problem: From college, I only have access to ports 21, 80, and 110. I cannot change the ports on my server, of course, as I have customers.

    My idea: If I can get SMTP working on port 80 for just one of my IP addresses, I can have usable SMTP. :D

    Question: A) Any better ideas? B) Is it possible? And if so, can someone point me towards the right places to edit? Assume I'd have to edit config files for exim; should I simply tell cpanel that the IP no longer exists, or do I have to figure out how to not use it for apache specifically?

    Any pointers/help would be greatly appreciated. And if you know of a tutorial for precisely this problem, I'd love a pointer to it. My searching turned up nothing related to this.

    EDIT: I've continued trying my best to help myself. Still hope for some pointers - maybe tell me if I'm headed the right direction.

    - I added the IP address to the apache reserved IP list. Will this mean that apache will ignore this IP now, freeing exim to bind on port 80 when I figure that out?

    - found this gem: http://forums.cpanel.net/showthread.php?t=64102 -- that might solve the issue, but I'm not sure of the command line options to bind it to IP 1.2.3.4 on port 80... :/

    Have you considered alternative solutions for allowing this user to send mail via port 80 such as using the webmail interface?

    If you are on cPanel 11.23 or later, upon logging into any cPanel interface, the system will see if you must use port 80. If so, it will serve content over port 80 rather than the usual cPanel/WHM/Webmail ports.

    Thanks for the reply! :)

    1. The user is me.
    2. As I use Outlook for email, it is very inconvenient to check my mail in Outlook, then log into webmail if I want to reply.

    I realize I *can* do this, and I *do*; I was seeking a workaround so I wouldn't *have* to, as that way is inconvenient to me. :)

    But I figured if I can bind smtp only on *one* of my server's IP addresses, on port 80 -- that would be a most excellent solution, as I could have Outlook authenticate on port 80 to that IP - and even get to use my real POP/SMTP credentials, I'd assume. :)
