    I followed your tutorial for the perfect server and everything works great.
    my isp (comcast) is blocking port 25.
    is there a way to change the mail port so that emails will send and receive on another port? i can send on port 587 using comcast relay settings but i can NOT receive and i dont get any error in the mail log.
    anyone knows how to change incoming port from 25 to something else?

    You can not change the port for your mx-sever. You must use 25 to receive mails.

    thank you for your response.
    do you have any advise on a work around for this? if i cant change the port anything that can be done other than upgrading to a business account which is slower and costs alot more.
    thank you

    There is no workaround for a blocked port 25 incoming, you can e.g. get a virtual server in a datacenter and host your server there.
