Re: You must have huge messages with lots of attachments/images
The images and attachments are stored separately, not in the database.
Yep, I forgot that. I stand corrected.
BTW, what about inline images? Are they also stored separately? I've never paid attention to that.
Could be a lot of accounts and/or a lot of folders and/or a lot of very large messages.
The OP talks about two accounts:
BTW, I have Messages to sync at 90 and Messages to cache set to 50 for both my accounts.
Kostya, why are you mentioning "a lot of folder"? Does that matter?
From a recent (different) thread, I understood that the number of messages to sync/cache is per account (combined for all folders). So, in this case, - there should be up to 180 messages cached (and synchronized). That's slightly over 1MB per message (on average). If the inline images are not included in that, - it is quite a lot, even for crappy HTML-formatted messages such as those generated by MS-Word.
