To increase email security on our network we have implemented a configuration change to the way SMTP AUTH works.

In the majority of cases this will not affect anyone. However we have had a small number of customers contact us because they have been affected by the change.

Basically we now only accept mail via SMTP AUTH when the sender email address exactly matches the SMTP AUTH email address.

To avoid any problems you must ensure that the ‘Email Address’ field in your mail client matches the email address used for your username when sending and receiving email. If these do not match then you will be unable to send any messages via AGUK.

In Microsoft Outlook this is specified as follows

Tools > Email Accounts > View or change existing e-mail accounts

Select email account > Change

Make sure that the ‘Email Address:’ field exactly matches the ‘User Name:’ field.

In Microsoft Outlook Express this is specified as follows

Tools > Accounts

Select email account > Properties

Under the General tab the ‘Email address:’ field must exactly match the ‘Account name:’ field as entered under the Servers tab.
