Hi, recently, we had a problem on one of our mail servers and, after reboot, HDD with emails wasn't mounted into system. Until we fixed it, LOTS of users logged in (Dovecot allowed login and recreated directory structure of mailboxes) and saw empty mailboxes. Now they are redownloading all email, which isn't fun, as it's about 2 TB of data. Anyway, is there a way how to prevent this in the future? Can i set Dovecot to disallow logins in such situations? Thanks. azur

...clinets started to download them again. Why this happened and how to prevent it (other than 'not hard-rebooting')? I know that reboot could cause corruption of uid files in some cases but this time it looks like this was caused by corrupted indexes - how index corruption can cause redownloading and why? Thanks for any info. azur

We had an issue today with IMAP clients (Thunderbird, Outlook) having to redownload headers for folders. This issue was eerily close to a MySQL database structure change that shouldn't have affected any related queries, however we did notice an event of user CPU % not being reported via SNMP around the same time for the server. There are no entries in our dovecot error log...

Hi, When I run make in libguestfs directory, supermin tries to redownload all packages it needs everytime. This is a blocker for me because: 1. I have a slow network connection, redownloading all packages is just a waste of time even though they are not big. 2. My network connection is not stable(especially when visiting sites outside of China), sometimes it fail...

TESTED AND RUNNING, MIGRATING from MBOX to MAILDIR, PRESERVE UID and OUTLOOK sees the email as downloaded. I hope this helps a lot of people out there. Feel free to post this somewhere else too. By: Horn Wijaya (hwijaya at nodens.biz) 8th May 2008 I have been searching for weeks for a foolproof method to migrate all my users mbox to maildir/dovecot without having the pain of downloading

Hi, today we have a problem our mail server about user accounts. (something about prefetch) anyway i corrected, but some clients re-download emails again. how can i stop this .I've read about some forums about UIDVALIDITY ? is it posibble prevent clients redownload emails with pop3 ? thanks in advance. -- Sel?uk YAZAR

...mirror server A on a regular basis, but at different actual times (due to TZ differences). Server D is mirroring Server B. We'd like to change Server D to be mirroring Server C instead. Previously when I've swapped between servers like this, vast swathes of the archive are deleted and redownloaded (I use -av --delete-after) for no reason other than the timestamp being different. If I use -av -I, will it ignore the timestamps and only go on file size? The archive in question is a several hundred GB linux distro archive so I'd rather not have to redownload it :) Cheers, Mark. - -...

...e doc tells to rundovecot --hostdomainto make sure the hostnames differ... To my surprise the command returned "localhost" on both servers. How do I set the hostname for dovecot service?(The hostname command returns the servers hostnames.)Will a change in dovecot hostname make all clients redownload all their mail? A second question. When configuring dovecot replication. Should the settings be done on the master server or the stand by server, or both? (Doc doesn't say anything regarding this) PG

I've tried every imaginable <loadinformation> parameter, and can't get the phone to actually grab the image, it just keeps redownloading the XML file.

If I rename P003-07-1-00.sbn to that name, it downloads the file but then says "File auth error". Anyone been in this situation before, or have any...

...of these messages and I will resync someday and then try to file them away more expediently than my previously somewhat lazy management style to keep the inbox small. * In thunderbird, I get constant downloading of messages. Every time I switch to the inbox from another folder, the messages start redownloading. This sometimes, but not always, seems to create duplicate messages, but I'm now fairly sure they are only created in the client and not on the server. Searching through various forums, it appears this has been a problem for Thunderbird for some time, but it wasn't for me on Courier....

Been using imapsync for large scale migrations from external servers to our dovecot setup. Users don't even see it when the key is switched (DNS changes). Go for it.

...done to death, but I want to migrate from Courier to Dovecot. I think my main question is whether there's any reason I shouldn't just rsync the maildirs across from the old mail server to the new one? There aren't many clients using this server, so I don't care if clients have to redownload all their messages (in fact, I expect they'll probably end up doing so anyway). I'd like to preserve read/unread status of each message, but can't think of anything else important. It doesn't matter if there's a few hours of downtime, but I thought to use rsync because I figur...

Hi dere, I switched over from Windows to Linux and I'm loving it. I do have a few problems with Gmod. 1. It won't work. I downloaded Wine after I downloaded Gmod, would that mess it up? Do I have to redownload it? 2. I also downloaded it from Steam, does that affect it? kthnx :D
