I realize that the main function of SA is to separate spam from
non-spam.
You've misspelled "only" there.
But I am encountering a growing need to sub-divide some non-spam mail
between important (keep) specific mail related to a purchase vs.
promotional mail from the same vendor. For example, we do a lot of
RVing. We make reservations sometimes months ahead at a campsite and
receive confirmation emails, etc. But we also like to hear about
other promotions and offers from the same camp site. I want to
expire and autodelete promotions-only email after a certain expiry
period while permanently keeping reservation confirmations/receipts.
It would be wonderful if these emails came from
"[email protected]" and "[email protected]". But
that would be too easy, and rarely occurs. Mostly everything comes
from info@... or some other common email.
You're looking for competent correspondents and procmail (or sieve.) SA
is neither of those.
I suspect this is a total long-shot. But just curious if there are
any tricks/techniques that others are using that can somewhat
definitively separate reservation confirmations from
promotions/marketing email so I can categorize lifecycle
accordingly? I suspect there may be some training per vendor. But
what is the best/recommended service to be trained? Any
suggestions welcome.
This is entirely out of scope for SpamAssassin, which is strictly
designed to make a one-dimension categorization.
It is *usually* true that you can find some clue in headers to
distinguish between different sorts of email from one organization. If
you cannot, it is because the sender does not see the mail as having
different classes or is intentionally trying to prevent you from
distinguishing their valuable mail from their garbage.
