Cannot send mail through Outlook express from remote location

When I try to send mail through Outlook Express from a location other than my home office, I receive the following message from McAfee Security Center:
Command received: 550 5.7.1 Relaying not allowed

Why can I receive mail but not send it?

Is there something I have to disable for relay to proceed? Please help.

 

Most providers block outgoing smtp to other servers to prevent spamming. You need to find the smtp server info for your second location and change it when you are in that location. Or check if your provider offers authenticated smtp, but thats unlikely.

 

I work on the road, so my remote locations change frequently and are usually hotels. Do I have to enter new smtp info every time?

 

Yes, or use/find a provider that offers authenticated smtp or webmail should work will out issues.
