Hi everybody, I'm trying to backup a dovecot instance, and i'm looking for a method to "snapshot" dovecot maildir in a properly way, and backup whole snapshot in a second step (tar). I read about dsync, end, if i'm not going wrong, it dumps correctly also dovecot indexes; is it the tool i need? Thank you for any hint. Ramon

[Dovecot] possible quota bug ?
by fernando.figaro＠uol.com.br 31 Mar '14

31 Mar '14

Hi, I'm using dovecot 2.2.5 with quota (maildir backend), zlib and expunge plugins. When I list maildirsize file, I get: 1073741824S 17952 16 If I receive a new message (example: 1204 bytes compressed and 2524 bytes plain text), the quota file is write correctly (2524 1 entry). When I move the message to trash folder (or between user custom folders) the file have wrong entries: 1073741824S 17952 16 2524 1 1204 1 (this is the size of the compressed message) -2524 -1 I coudn't find any relation with the config settings causing this problem and checked the changelog since 2.2.5. Had someone had this same problem? Thanks, Fernando

[Dovecot] pop3 mailbox mirroring issues using dsync
by Nikolaos Milas 30 Mar '14

30 Mar '14

Hello, I have setup v2.2.12 to mirror mailboxes between our main mail server (vmail.example.com) and a failover server (vmail1.example.com) The problem I have is the behavior of mailboxes used on the main server (*vmail*) over POP3. I have setup an IMAP account on the failover server (*vmail1*) on such a mailbox: the mailbox is used on vmail using POP3 and the same is monitored on vmail1 using IMAP. It's mailbox *userx*(in Maildir format). I notice that all mail coming in userx mailbox on vmail, is correctly replicated on vmail1, but when it is downloaded from vmail over POP3 (and the mailbox there remains empty), the same mailbox on vmail1 is not updated to be emptied (automatically) as well, but it is accumulating mail forever (which is real problem on the mirror server). Is there a setting to enable correct mirroring of a POP3 mailbox (to empty the respective mailbox on the failover server) when mail is downloaded from it or something else should be done in this respect? Please explain. I quote below the full current config on the main server.

[Dovecot] basic dsync wrapper for migration from another server
by Alan McGinlay 29 Mar '14

29 Mar '14

Hi, I cobbled together this somewhat shoddy Bash script to migrate email accounts from our Cyrus server to a new dovecot system. Feel free to use, or laugh at it as you wish :) #!/bin/bash ## # Migrate email accounts via IMAP from one server to another ## trap "kill 0" SIGINT workdir=/root/migrate # Load list of users into array. The file "migration_map" should contain one user(a)domain.tld per line. mapfile userList < $workdir/migration_map # Number of symultanious migrations num=10 index=0 # Loop over the array of user accounts function process_userlist { procs=$(ps aux | grep "dsync" | grep -v "grep" | wc -l) # Perform $num operations at a time for the length of the userList while [[ $procs -lt $num ]] && [[ ${#userList[@]} -gt $index ]]; do procs=$(ps aux | grep "dsync" | grep -v "grep" | wc -l) dsync -o mail_fsync=never mirror -f -R -u ${userList[$index]} imapc:& echo "procs: $procs user: ${userList[$index]} index: $index" let index++ done } # Until the userList is empty, keep going until [ ${#userList[@]} -eq $index ]; do process_userlist done exit 0
