Why are you "syncing tens of thousands of messages to an IMAP server?" Did you backfeed all your local mail archives back out to the server?
Mail's IMAP defaults are tuned to pure cloud-based operation, which frankly most people do not need. Sure, being able to access any piece of mail or any draft created on any device from every other device you own is a "cool feature," but most people are never going to need it or use it, and the overhead is massive. Turn off "keep sent mail / drafts / trash on the server" and your overhead goes down considerably. Same goes for keeping named archival mailboxes on your server. I see you are a gmail user — perhaps you are suffering the technical consequences (never mind the privacy consequences) of gmail's default "keep every piece of mail that ever crosses our threshold forever" design. If you dig down into the POP/IMAP configuration page at the website, you can turn off that behavior and then manually trim your "permanent record" at gmail back down to a reasonable level by pruning your "all" mailbox. > On Jan 19, 2016, at 11:23 PM, Matt Penna <[email protected]> wrote: > > For what it’s worth, I finally switched to IMAP after nearly 20 years of > using POP and the experience has not been good.
