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
