I mentioned a couple of months ago that my "personal" inbox had crossed the 20,000 e-mail mark; I've now just passed 22,000.1 I'm fairly certain that the app itself doesn't have an upper limit, and so I'm curious to know, what's the largest usable Mail.app mailbox out there (and by "usable" I mean a mailbox that's being hammered on a daily basis)?
I'll keep updating this post with the largest number I receive.
Currently, the largest number is 283,686 (I required screenshot proof of this one).
I've had a lot of people e-mail me about the fact that my e-mail doesn't seem to be sorted in any particular order, but is instead all lumped into one big folder (or two, sent/received). This actually isn't the case — I use Mail Act-On (something I'm sure to write about in the future) in conjunction with a fairly elaborate system of smart mailboxes (scroll down a bit after the jump), which leave the mail in its original folder, but replicate it across the "smart" mailbox. ↩
