SMTP settings in Outlook when on the move

[Anchundan]

My company email uses a simple setting for sending and receiving email.

Incoming mail server (POP3) : mail.xxxx.com
Outgoing mail server (SMTP) : xxx.com

In more settings, Advanced, the outgoing server port is 25.

In most cases when working away, I can send email normally, without having to change the settings. But once in a while, I won't be able to send anything from a certain location.

From what I have gleaned (and I really don't know much), some server administrators block port 25, and this is probably why in certain locations I can't send mail. Is this correct? And if so, how can I get round the problem - would specifying a different outoing server port number fix the problem?

Assuming your SMTP server supports a 2nd SMTP port, then yes it might well help.

Some ISPs block access to port 25 outside their networks and we often block outgoing port SMTP on networks for anything other than the mail server.
