Hi all Does anyone know what email authentication is? I've just received this from BT Yahoo! Internet. Reminder: please authenticate your email! We've introduced email authentication To help reduce abuse of your email service and spam (junk email), we've introduced authenticated email sending (known technically as 'authenticated SMTP' or 'SMTP server authentication'). If you haven't yet made sure your settings are configured to avoid possible problems sending email, please do so NOW. What you need to do Email authentication means you need to make a small change to your email program's settings (e.g. in Microsoft Outlook Express) in order to send your email as usual. ------------------------------------------------------------------------ Now the problem is, I floowed the instructions what to do, but then found I wasn't able to send mail, so had to change back. So I am supposed to set up for email authentication, yet that stops me from sending mail. Regards, Derek e-mail: derek.hornby_uk@xxxxxxxxxxxxxxx ** Going on holiday and want to halt messages?
