Our mail server may send various informational email messages to both local users and remote senders. This is a partial list of the more common messages, and a brief explanation of each.

Banned name in mail to you

Someone attempted to send you a dangerous attachment, most likely an executable (ie, a computer program). There's little reason for an executable to be sent via email, so the message was blocked by our mail filters. If you were expecting the attachment, you should ask the sender to archive the message in a ZIP file and send that. If you weren't expecting the message, then it was probably sent by a virus, and you can ignore the notice.

**Virus in mail to you**

Someone attempted to send you a virus, but the mail filter recognized it and blocked the attempt. Most such messages fake the sender and choose a recipient at random, so if you weren't expecting a message from the person, you can safely ignore the notice. However, if you were expecting the message, then the person may have an infected computer -- a small number of viruses will infect legitimate outgoing messages.

Permission denied

Some spammers bypass our mail filter server, and directly connect to the internal mail server. In this case, the mail server should catch this, and return a "permission denied" error to the supposed sender. Unfortunately, since many spammers fake the sender's address, the wrong person may get this message.
