I have added an entry to my mail-from Blacklist, and noticed emails still getting through. While researching, it looks like SF recognized the envelope-from field as the mail from field, and allowed the message because the address is different. Which should I be blocking? I would think that I should block the mail from, since that's what most users will report to me. I've posted the headers and the log below to show you what I mean: Logs:

I noticed the same thing the other day - but the emails were from myself.
I had a PHP script that was emailing me some info, and it was being blocked because of an invalid MX record. The sender in the from field was support@mydomain.com, but SF was blocking the email as it was using the sender it found in the headers as apachie@s90.mydomain.com which of course does not have a valid MX record. I have not figured out how to set the from in the headers of the message. I can whitelist the IP, but that does not solve the underlying issue for me. |

The only sender's email address that matters to SpamFilter is the one given in the MAIL FROM command. That is sometimes indicated as the "envelope" or "return path" address. SpamFilter will add the address that was specified by the remote server during the SMTP session in the following header to incoming emails:
X-SF-RX-Return-Path The address that is specified in the email's "From:" header is ignored and not used by the various filters. |
