Port 25 blocked by ISP

My ISP blocks port 25.
What's the best way to get around this?

Tnx,
So the only thing I have to do is

Uncomment?

Quote:

submission inet n - - - - smtpd

and restart Postfix?

How should I test it?

if you are not using a firewall than that is all you will need to do on the server.

Make sure that you setup the client to use the SMTP port 587 instead of port 25

Port 587 is open, checked by http://www.yougetsignal.com/tools/open-ports/
Postfix restarted.

Test with (squirrel) webmail but email is not delivered yet?

It looks like mail is sent but it's not arrived in the mailbox?

Are there any things I can check, config or test?

Changed Squirrelmail

Quote:

/usr/sbin/squirrelmail-configure

to use smtp port 587 but still messages don't arrive to destination.

Did you configure an email account in ISPConfig?

What's in /etc/postfix/master.cf? What's the output of

Code:

netstat -tap

I'm trying to use smtp2go and critsend as relay smtp service.

The servers queue is very full and a lot of mail get's send. But the biggest problem that a lot of mails get bounced (and the services disable my account)

Quote:

554 5.7.1 <root@mail.myserver.com>: Relay access denied

What can I do about this?
