How to configure router to send email logs to a smtp server who has blocked port 25?

Hi. I need to send emails with logfiles from my Zywall router to my email. I can easily access a menu where I can specify smtp server, email of the sender and of the receiver, smtp authentication parameters, but I cannot specify the port. I.e. I assume the Zywall router uses port 25 to send its own emails.
The issue is that my IP provider blocks port 25... and would like me to use port XXX instead.
I assume there can be some advanced function, where I can reroute all outgoing smtp traffic to port XXX, but where can I find it?
Thank you for your help!

Fantastic, it worked! Thank you very much for your help. I will just add a short comment, which may help someone else.

First of all, I had to find a program to connect to the Router. I downloaded PuTTY and I recommend it. I used telnet to connect (SSH gave me problems).

Secondarily (and finally) it took me some time to find the CLI - I had to choose "System maintenance" (item  24 on my menu) and then "Command Interpreter Mode" (item 8 on my menu)... that was it.

Again, thanks!
