I've been running UoW at home for years, where it has a single account. While it generally works well, I find that if I leave Seamonkey mail running and then access my mail from another computer with either Seamonkey or Thunderbird, the Seamonkey on my main computer often locks up, though for some reason, accessing my mail from my Android phone does not cause this. I have seen some hints in the Dovecot docs that it will fix this sort of problem. So, I may change my home system from UoW to Dovecot, when I upgrade to a newer version of openSUSE (currently 11.0). >>>>> I assume there should be no difficulties in switching to Dovecot since it and UoW both use mbox. <<<
Bingo!... That's a reason why I avoided 'Cyrus' like plague, and why I moved to dovecot... Dovecot is much better about handling multiple accesses.
False. Cyrus handles concurrent access *VERY* well. And recent 2.4.x releases have dramatically improved performance beyond what was available in 2.3.x
W/mbox, I have 458 mail folders under 29 dirs with 212638 messages dating back to about 1995...**
I don't think what you are describing is mbox. MBOX: "All messages in an mbox mailbox are concatenated and stored as plain text in a single file" What you are describing is maildir or maildir+ or maybe MH
With Cyrus, that would be about 487 directories, with 212638 files. -- w/each file rounding up to the 4k fs-block size. Um...and somehow, doing a search on that w/ 200K opens .. seemed like a recipe for poor performance.
Or a search on Cyrus would use the SQUAT full-text index and be very fast; or a meta-data search would use on of the maintained meta-data databases and not walk the message tree either.
yeah, Cyrus would have been faster on that stat using 'find mail -type f|wc -l', but any other filtering?
And doing any such thing is bad. If you have an IMAP server you should access your mail via the server. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org
