manually train Bayesian Filter
Is it possible to manually submit known-spam and known-good messages to Bayesian Filter? Using thresholds is useless - most of the spam that we receive, scores around 5. Plus there is no way to correct a mistake.

Log in to your frapper.com DNS zone.
Add a new CNAME record.
Enter "pics" as the Name.
Enter "pics.ribbit.com" and the Content.

Re: Filter based on From matching X-Envelope-From
This is very helpful. I can at least mark the message as a suspect. Thank you for the tip. I, personally, want to know when the From address that I see is spoofed. There are valid reasons to do this sometimes but this should raise a red flag. That's why, in my opinion, SpamAssassin should have test ...

Filter based on From matching X-Envelope-From
Is there a way to filter messages based on whether From header matches X-Envelope-From? Either during SMTP phase or SpamAssassin rule or Sieve script? So many spam messages are just send from a valid source passing SPF but with fake From header.

SpamAssassin only scans messages less than 128KiB
SpamAssassin only scans messages less than 128KiB. This limitation effectively skips spam messages with attachments. And if the attachment is an archive then antivirus will not scan it either. This reduces protection greatly. Is there a way to make SpamAssassin scan a message with attachment even if...

"exp" modifier in sender's SPF
Do rollernet SMTP servers recognize "exp" modifier in sender's published SPF record? It seems that they ignore it and return standard "SPF Fail" message.
