    Hello,

    I`m currently using port 25 for SMTP outgoing mail server but i get complains from big ISP form several users that their ISP is blocking port 25. Is if possible to setup my SMTP server to respond on second port at the same time and if it`s possible how to do it ?!

    Thanks

    Sure thing, in WHM > Service Configuration > Service Manager, you'll find an area there called exim on another port.

    For example you could use port 587 here, tick both boxes there and save. You'll also need to open that port in your firewall, and of course explain to your users how to change this in their email clients.


    Easy stuff, good luck. :)

    THANKS FOR THE EXTRA FAST REPLY! I was not expecting it so fast!

    Just to conform. This will not change default port 25 for outgoing mail server? It will just add second port ?!

    No, you cannot disable outgoing port 25 if you want exim to still function properly.

    please block the port 25 on the server firewall and check the exim service is running fine.

    There's a huge difference between exim running and exim functioning properly. Exim will run with the port blocked but it will not properly function. Please do not recommend poor configuration options that will prevent emails from sending out of the machine. If port 25 is blocked, you will need to use a router to route everything on the other port. It isn't just a simple matter of blocking the port and expecting exim to function correctly.

    After port 587 is setup for SMTP in Exim, how can one update the the "Configure Email Client" page and add port 587?
    Outgoing Mail Server: mail.server.com (server requires authentication) port 25 (if ISP blocking port 25, then use port 587)

    Reads like you're asking to have the wording changed there?

    Hello,

    Sorry about reviving a slightly dated thread, but its pretty close to my inquiry.

    I have a problem in that users on my server are being prevented from sending mails because their dynamically assigned IP's are listed in spam lists.

    I have turned off the option in WHM to check against these lists as a temporary solution, however that is obviously not ideal.

    If I turn spam checks back on, then tell those clients having problems to use port 587, does that skip the spam checks on the server?

    I hope I'm clear...

    Regards,

    John
