That makes sense. So you're saying that very large inboxes are generally bad for mobile devices? How are they bad for the servers?
I'm saying that large inboxes can be generally bad for MUAs including mobile and desktop. Their just downloading and constantly grinding through data that isn't really being used. Same thing for the server.
If you have an inbox with 10K emails, are you reading them all? No, but you are likely checking the inbox every 5 mins.
And if you have a 20GB INBOX and you download it on mobile, depending on the MUA and settings, you might be just using a ton of cell data and storage on your phone.
Dovecot, of course, has intelligent caching and that helps a ton but overall it's an efficiency thing. Though not that long ago, it was also a way of keeping some MUAs like Outlook from crashing when the PST / OST file got too large.
