    I use WHM, and im unsure why one of my resellers have an account, and his unable to connect to SMTP on port 25 anymore. It seems it only form this IP so could he be banned? We found that he cant even make a sucsesfull connection to the server on port 25 but has no problem on port 80. If he is banned from only port 25 how do i un ban him?

    THis is more than likely an issue with his ISP.

    Many ISP's are disallowing their users to connect to SMTP servers via port 25 in an effort to reduce SPAM.

    IN WHM, there is an option to enable ENSIM to run on port 26, so he could then connect via port 26 (so long as he changes his email client settings). As well, if you have a firewall installed, you would have to ensure that port 26 is open.

    Hmm....

    Perchance, does he run a firewall on his PC? I have one client that constantly "plays" with his office firewall and calls at least once a month claiming he can't connect to the server. I just have to remind him to check his firewall and he is then a happy camper:)

    I have a stupid question. :) If you enable port 26 for smtp will port 25 still work or does Exim shut it down?
