Problem with club email addresses

Our club President has been experiencing some problems sending emails using the club addresses on the website.
She recently had to email TI using their web address and experienced the same problems. However, she managed to capture the error message, which is:

The host 'vped@arunspeakers.net' could not be found. Please verify that you have entered the server name correctly.
Subject 'ASC - Test Email', Account: 'AOL', Server: 'vped@arunspeakers.net', Protocol: SMTP, Port: 25, Secure(SSL): No, Socket Error: 11003, Error Number: 0x800CCC0D

Any help or advice much appreciated,

Many thanks

She needs to contact her PC support or AOL. Her mail client is not set up correctly.

Just checking something... You are not trying to use the officer email addresses to *send* email from, are you? Those are receive only.
