Problems with e-mail notification from this forum

Hi,

for two week or so I don’t get e-mail notifications for posts and address verification from this forum.
After changing to another e-mail account (gmx.de) the notifications arrived.
So it looks like something is wrong with the first account.
BUT: The mail for verification from the avast support desk does arrive at the first account (freenet.de)! And messages from everywhere else do arrive, also.

Since I use this account for notifications from all forums I’d like to keep using it.
Does anyone have an idea what the problem and a solution may be?

Thanks.

Have you checked your spam folder?

Thanks for the answer.
Sure did I.

Try http://www.avast.com/contact-form.php?loadStyles (Website or Technical issues); that way someone might actually check.

Thank you, I did as you suggested.
If there is a solution I will post it here.
