## Anonymous Sender

There is a problem with:

> %mfrom

The HELO name, `%helo`, is invalid (does not resolve to `%ip`). There is no valid PTR record for `%ip` (does not exist or does not resolve to `%ip`. Dynamic names for HELO or PTR do not count since you have no Sender Policy either.

Contact your mail administrator IMMEDIATELY! Your mail server is severely misconfigured. (If you have a dynamic PTR/HELO, it is technically correct, but most email services reject dynamic PTR because it generally indicates a "bot", a compromised home PC that sends spam.)
