Gentoo Postfix Isp blocks port 25


so my isp blocks port 25 so i'm using port redirection service to port 26 which has been working fine receiving email. The problem is that when i try to send email it trys to send out on port 26 so of course it times out. I changed the smtp port in /etc/services but that doesn't seem like the right way to go. You guys have any suggestions? Thanks for your help.

ahh well i'm not sure thers is much you can do about this. port 25 is SMTP so every other mailer will use this port. The only thing I can suggest is to find a relay that can use an alternate port and set the relayhost setting in postfix with this address

Do you think i could do this:

but instead of 2 ips just use a port number?

i don't think this wil help. you can alter the incoming port and then use fetchmail to retreive your mail - this would obviously mean you can't run a live server but that may not matter. When it comes to sending out the mail though your system is going to have to send to the recipients server on port 25 (that is they port thay have set, you have no control over that)

Probably the easiest way is to set your isp up as a relayhost. they will accept port 25 requests to there own server so that should sort you out.
