Weight message that aren't addressed to recipient?

[thunder04]

Hi All,

Is it possible to give an e-mail that isn't to, cc, or bcc, the recipient a higher spam score? If so, what would be the best way to do it?

Edit: Boy, my grammar skills are really working today!

Hmm...nothing...not even a pointer in the right direction?

Hmmm...

Why would you even accept messages that aren't addressed to a valid recipient?

[thunder04]

The problem is we're receiving spam that, in the headers, doesn't display the recipient's e-mail address. I'm not sure if this is due to the spam being BCCed to the recipient, but typically the headers will show a "To: x@x.x" that is random and not even part of our domain.

If I'm BCCed an e-mail, would the BCC show in the e-mail's headers?

No it wouldn't hence the name BCC :P

[thunder04]

Yeah...just verified this myself. Feelin' kinda stupid right about now!

[thunder04]

Another question is...

How does BCC work, exactly? Where do the BCC addresses get stripped from the headers? When the e-mail reaches it's destination?

[ArcaneMagus]

The MTA (Postfix) handles all of the details like header re-writing and transferring to the correct addresses.

Ah, got it!
