Thanks for reply
The solution described above is using SMTP provider server which is using
standard 25 port for outgoing mails.
I need change it to port 2525.

Thank you

Ok. But in step four you can easy redirect port 2525 to 25.
If you really want to change smtp port, I think you need to adjust some configuration in masq file (iptables), and smtpd service configuration.

As I understand I can redirect only incoming ports from outside to the server. I did it for incoming mails and it's working just fine.
The problem is that I'm going to use DynDNS MailHOP outbound mail services to bypass port 25.
They require using user name and password for SMTP connection.
So what I need is change outgoing mails to port 2525, add user name and password.
It's working if mailhop is defined at mail client as a outgoing mail server, but in this case I can't use webmail. It's still trying use port 25

Any suggestions ?

Title of this thread should be "Outbound Port 25 is blocked".

I gather you have confirmed this with your ISP and there is no way to unblock it if you promise to be really really good? Optus in Australia has this 'feature'.

IF I give advise.. It's only if it was me....

We have the same situation.

We simply send out emails to our ISP's relay.

Never an issue.
