The mailservers are running spamfilters and other filters that help cut down the amount of spam our customers receive. If your mailserver is correctly configured and you don’t send spam or “opt-in bulk e-mail”, our mailserver will happily receive and send your mail. However, if your mailserver isn’t correctly configured, the mail you’re sending will might bounce back to you.

If you’re a mailserver administrator, please contact our postmaster directly. If you’re an end-user, please contact your mailserver administrator and have him/her contact our postmaster.
