end of log.

could some nice person explain or guide me how to get this working.
ive earlyer been into master.cf and changed port settings to 685,2525 and so on but
nothing worked for me im kinda new into postfix and email settings, i did lookup in this forum
but i had no luck so far with my settings, thats why i made a frsh install.

Howdy,

What problem is it that you’re trying to resolve exactly
 are you trying to find a way around the issue of your ISP blocking port 25?

I’ll offer that if I try to connect to port 25 on your server, I do get a “Connection Refused”.

If that’s the problem you’re trying to resolve – unfortunately, you’re kind of stuck. You’d need to have an ISP for your server that isn’t blocking port 25.

While it’s possible to have Postfix listen on an alternative port, a sending email server won’t know to use that port. So, in order to receive email from a mail server, port 25 would need to be working.

Hi and ty for your answer.

Ty thats what i thought aswell but my ISP keept telling me i could use there mail1.stofanet.dk
through postfix,

i was thinking is there a way to keep my old isp and use them as mailserver (port 25 not blocked)
and at the same time use new ISP for traffic, my old isp was a 10/1 Mbit and the new is a 111/11
the extra upload really boost my system or do i need to mke a choise and skip email server here.

Is that possible ?

Ty.

It is true that you can use their mail server via Postfix
 but that’s only for outgoing email.

There’s no way for your server to receive incoming email from other mail servers on the Internet if port 25 is being blocked.

So yeah, it does sound like you’ll have to make a choice between which functions you want :slight_smile:
