âmanage [*] subscriptionâ gets some of the sneakier ones too
Which mail package allows you to code âFrom: is not from any of my address booksâ?
Appleâs Mail app, for one (you can select âsender is in my contactsâ as a rule predicate).
I would guess some version of this is in Outlook, Thunderbird etc. too
Are you the one person on the planet using Appleâs mail app?
No, he isnât - if you trust this link, then around 5% of emails are sent with Apple Mail: https://emailclientmarketshare.com
From which we can conclude that either Apple mail users are incredibly closed-lipped or the rule is irrelevant for only 95% of people.
I work at a fancy university, and an alarming amount of the faculty use Apple mail. I therefore have to support it. I therefore often feel dead inside.
Whatâs wrong with mail.app? For simple mail usage it works fine. Iâve been using it for 9 years with multiple accounts, tens of thousands of messages, and it rarely causes me any problems.
Um, probably all of them?
Even a creaking old antique email program like Eudora has a filter setting for âintersects/does not intersect with address bookâ
Eh, Mail is reliable and stores my stuff. Couldnât ask for much more than that.
Cory uses Thunderbird, doesnât he? So perhaps that?
procmail+python?
I just checked, Thunderbirdâs filters do allow âis/isnât in my address bookâ.
Only problem I see with this is that itâll also hit on a lot of stuff I normally get from companies I actually want to receive from, unless I add them to my address book⌠and making sure I wouldnât miss any of 'em that arenât already in my address book would require much more regular/complete scans of my junk folder than I currently do.
There isnât anything âwrongâ with it. Itâs just some people believe that anything Apple makes is bad and therefore has no merit. Sometimes these same people will state that Outlook is so much better even though it doesnât seem to work that well as an email program in the first place.
No. I actually own a Mac as my primary laptop, and I donât use the app. My choice was based off of issues I had with it over a decade ago, so if itâs awesome now, please let me know. Otherwise I donât have the time to look into it.
I use both mail.app and Thunderbird. Both work fine on OS X.
I use Gmail which has a lot of mail filtering features, (yes I know. I do use gpg and a different system that I trust for anything important.)
At work I use outlook, and it has the most extensive (but not user friendly) feature set I know of for filtering. It also replicates a filesystem for your email, implemented as a completely opaque binary blob in the windows filesystem. Which is awful. But hey at least the whole thing is encrypted. Even if the whole thing is encryptedâŚ
I use fastmail, which isnât own by a giant corporation that makes money off of selling my data. 
I ought to switch, but by now there are so many people and small businesses I have entrusted with my Gmail address that it seems like more trouble than itâs worth to switch abruptly.
