Hi

My ISP is the Spanish company called TERRA.

I have recently installed AVG ANTI-VIRUS on my computer. It has a plug-in
which requires me to change my POP3 to 127.0.0.1 and my SMTP to the same. I
have to change POP3 port to 5100 and my SMTP port to 5101.

I can receive email OK and the virus checker checks my incoming mail.
However, I can not send mail to any other ISP. I get the following error
message:

"Delivery not allowed to non-local recipient, try authenticating"

I have gone to TOOLS, ACCOUNTS, MAIL, PROPERTIES, SERVERS, and I put a Tick
in the box "MY OUTGOING MAIL REQUIRES AUTHENTICATION" I then went to
SETTINGS and put my account name( name.terra.es) and password.

I can then send an email which passes through my AVG VIRUS CHECKER to any
TERRA email address.
When I try to send an email to my friend in England, I receive this message:

This is the AVG E-mail Scanner program.

I'm sorry to have to inform you that the message returned
below could not be delivered to one or more destinations.

Your e-mail message is being returned to you in the next part of this
message.

I would be grateful for any help.

Thank You
