Some incoming mail rejected

Between September 1 and September 15, some incoming mail was incorrectly rejected as spam. A blacklist incorrectly included all mail servers, raising the score of incoming messages, and causing some high-scoring messages to be rejected at the SMTP stage. See Debian bug #641227.

Since these messages were rejected before their contents could be accepted, they cannot be recovered.

Email senders should have received a non-delivery report (bounce message) that stated:

Client host rejected: Mail appeared to be SPAM or forged. Ask your Mail/DNS-Administrator to correct HELO and DNS MX settins or to get removed from DNSBLs;


Client host rejected: temporarily blocked because of previous errors - retrying too fast.

We apologize for the inconvenience.
