I have some rules that score 0.001 for this (like 'message body does not contain "transaction-id"' for example), then I have a filter in Thunderbird that stuffs messages from that vendor and with that rule in the headers into a folder where messages expire after a set period (60 days in my case).

I realize that the main function of SA is to separate spam from non-spam.  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.

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.

Thx

Jerry
