mail problem

[joximu]

Hi Lucian0308

Can you explain in a more detailed way what's the situation and the problem.

Your ispcp-Server is located at a housing provider or at home???
Your internet access provider does not want you (at home) to send mails to port 25 on any ip?

Ok, if you have spcp at home and you cannot use port 25 to send mails then there's no chance for this server to send the mails directly to the recipient - you need a smarthost (normally the smtp-server you get from your internet access provider) - maybe with SASL and port 587... this server then sends the mails to the recipient...
check the postfix docu...

ok

i have a small internet connection bussines
used for internet, not for webhosting
and my isp have port 25 closed

now i want to send emails on port 26 or other 2525
and by default it send on port 25

[joximu]

we speak about the port 25 on the target server, don't we?
eg. your server wants to send a mail to gmx, it connects to port 25 on mx[01].gmx.net...

And theese connections are dropped by your provider?

Then you cannot do anything - you need a smarhost. Because gmx does not listen on port 26 or 2525 or whatever... except maybe port 465 if you use a secured protocol (smtps) - but not all mailserver can handle this.

OR:
or are the connections dropped which *come from* port 25? then you can change to a different.

if i telnet to any mail.domain.com in port 25 i get connectin failed

means that port 25 is disable and i can't don anyting

a have another "smarthost", can i use that smtp server
for this server with isp 1.0.7 ?

[joximu]

you need to configure your postfix to use your smarthost...

If you use SPF records in the DNS remember to include this smarthost in the list of allowed mailservers...
