    Hi Guys

    I have my home server

    Problem is that my isp started blocking port 25.

    I Found that many dynamicdns provider have a way to redirect port 25 mail to other ports

    I have dns server working Fine.

    but i m unable to find where to put that redirect port 25 to other posrt.

    Also mail server supports imap.

    but i m unable to recieve imap mails Port of imap is open

    I m unablke to recivece emails too even the port 110 is open.

    why .

    if isp blocks port 25 then pop & imap also stop working ?

    Server : windows 2003 R2
    DNS : MS Dns

    thanks

    a partial help or inspiration

    i had a similar situation whle travling some ISP blocvk port 25 ( not 110 though )

    and i have my root server remote - Linux - using postfix,
    and made from my local machine a port forwarding to bypass my ISPs block of port 25

    the command line in shell i use locally is

    ssh -L 33888:localhost:25
    username@xxx.xxx.xxx.xxx
    Code (markup):
    above incl code ONE ine!!

    username = MY login at remote server ( NOT mailserver !!)
    xxx.xxx.xxx.xxx = my remote IP
    I am quite sure it also works with domain name + dynamic IP forwarding

    to send mail my localmachine ( =localhost) now has as mailserver ( smtp )
    localhost
    port 33888

    ( any other FREE port will do, check your system for free ports )

    same procedure works also for pop server port 110

    there might be a solution for you above - jsut read the manuals and howtos pertaining to your precise mail server software and server potential. I am lucky Linux user - hence zero problems.
    you are win user - for a reason i hope.

    good luck

    this procedure/functionality normally is called
    portforwarding or port forwarding

    a Google search for
    windows server port forwarding

    may give you more precise help ... hopfully
