Hi, all. I've been so impressed with Dovecot, I'm in the process of moving my mail over to it. In fact, one of my mailboxes got SO huge, it'll likely literally take more than a day to move it all over (in excess of 19,000 mails, about 140 megabytes). So far, the IMAP server shows absolutely no sign of crapping out yet. It should also be noted that I'm moving all this mail out of a Cyrus mailstore into an mbox folder on the same server using Pine. And at work, for my work mail, I recently installed Dovecot 0.99.8, using the POP2 port so I can have test it out while not disturbing my coworkers' ability to retrieve mail. So far, I have yet to see anything bad happen. My IMAP test is taking place under Debian GNU/Linux Woody and my POP3 test under FreeBSD 4.7-STABLE. Though any suggestions in what to keep an eye out for in either case? --Ian.

I don't think the amount of messages or their sizes should affect Dovecot. Except there's probably a few problems that could happen once UIDs are close to their maximum value (4GB), have to fix those some day.> It should also be noted that I'm moving all this mail out of a Cyrus > mailstore into an mbox folder on the same server using Pine. > > Though any suggestions in what to keep an eye out for in either case?Huge mbox files aren't very good idea if you plan to delete old messages or add new custom flags, they may result in pretty large copying of data.
