For some reason my links program has stopped emailing me with new links and I can't email validations or delete messages either.

It was working fine and the script hasn't been touched. I've even asked my web host to rese the server and he has, but still it doesn't work. All of my other smtp cgi scripts are working fine.

I've double checked the links.cfg script and smtp is defined ok as well as the $db_email_add = 1; etc.

Anyone got any idea why this could have happened? Cheers

P.S. I should probably add that the script confirms that the emails are being sent successfully.
