Yes. I used .maildelivery before procmail, and procmail until my work stopped supporting it and I now use 0365 rules and Google filter rules.
I would love somebody to write up seive and how to use it with the majors.
I use Google filters for what we used to call presort Inc, so I process list mails into specific folders, and identify a small handful of chums so I can always find their mail quickly.
Lack of decent support for envelope sender/recipient distinct from To/From field is a bugbear, the box.extra@ and box+extra@ method does most of what that needed but not all.
