I have three gmail accounts of which at least one carries 3.5gigs of mail. I've setup all the mail accounts on mail.app(3.2) as IMAP. The two small accounts run flawlessly but the big account has too many problems. For starters, it's literally always downloading mail and sometimes it just refuses to synchronize stating that I have a "server issue". Then I came across an article in gmail help that IMAP times out with big folders. I didnt want to loose my mail so I archived the mail in Gmail's all mail. My question is that if mail.app will still download/sync mail from my 'All Mail'(archived) folder or not. And if it does, how to bend it so that it doesnt. All suggestions will be welcome because at the moment Im pulling my hair out!
