[Dovecot] Dovecot-2.1.14 - pop3 processes always hangs forever
by Axel Luttgens 08 Feb '13

Hello, I'm currently experimenting with the 2.1.x series and am facing a behavior I can't explain; I must be doing something wrong and probably miss the obvious... ;-) This is a very basic build on Mac OS X 10.8.2: ./configure --prefix=/_COD/dovecot-2.1.14 --sysconfdir=/_ETC --localstatedir=/_VAR --with-sqlite --with-ldap=yes (Yes, I know, a strange layout, yet very convenient for testing various things here.) Dovecot's configuration is very basic too: # 2.1.14: /_ETC/dovecot/dovecot.conf # OS: Darwin 12.2.1 x86_64 auth_verbose = yes disable_plaintext_auth = no mail_debug = yes mail_location = mbox:~/mboxes:INBOX=~/mboxes/inbox passdb { args = /_ETC/dovecot/db.conf driver = sql } ssl = no userdb { driver = prefetch } It is started from launchd with the -F flag. Two users are defined in the database, user1 (100002/100002) and user2 (100003/100003), with "virtual" uids/gids. Connecting for the first time as user1 through imap: $ telnet 127.0.0.1 143 Trying 127.0.0.1... Connected to localhost. Escape character is '^]'. * OK [CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE IDLE AUTH=PLAIN] Dovecot ready. a login user1 pass1 a OK [CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE IDLE SORT SORT=DISPLAY THREAD=REFERENCES THREAD=REFS THREAD=ORDEREDSUBJECT MULTIAPPEND UNSELECT CHILDREN NAMESPACE UIDPLUS LIST-EXTENDED I18NLEVEL=1 CONDSTORE QRESYNC ESEARCH ESORT SEARCHRES WITHIN CONTEXT=SEARCH LIST-STATUS SPECIAL-USE] Logged in b logout * BYE Logging out b OK Logout completed. Connection closed by foreign host. In mail.log: dovecot[2997]: imap-login: Login: user=<user1>, method=PLAIN, rip=127.0.0.1, lip=127.0.0.1, mpid=3006, secured, session=<EOWWzjbVxQB/AAAB> dovecot[2997]: imap(user1): Debug: Effective uid=100002, gid=100002, home=/_Data/Mailstores/100002 dovecot[2997]: imap(user1): Debug: Home dir not found: /_Data/Mailstores/100002 dovecot[2997]: imap(user1): Debug: fs: root=/_Data/Mailstores/100002/mboxes, index=, control=, inbox=/_Data/Mailstores/100002/mboxes/inbox, alt= dovecot[2997]: imap(user1): Debug: Namespace : /_Data/Mailstores/100002/mboxes doesn't exist yet, using default permissions dovecot[2997]: imap(user1): Debug: Namespace : Using permissions from /_Data/Mailstores/100002/mboxes: mode=0700 gid=-1 dovecot[2997]: imap(user1): Disconnected: Logged out in=8 out=362 While logged in (ie after the login and before the logout), "doveadm who" shows: username # proto (pids) (ips) user1 1 imap (3093) (127.0.0.1) So far, so good. Now, let's connect as user2 for the first time, through pop: $ telnet 127.0.0.1 110 Trying 127.0.0.1... Connected to localhost. Escape character is '^]'. +OK Dovecot ready. user user2 +OK pass pass2 and the session hangs forever. This is written in the log: dovecot[2997]: pop3-login: Login: user=<user2>, method=PLAIN, rip=127.0.0.1, lip=127.0.0.1, mpid=3113, secured, session=<GTOlMjfV3gB/AAAB> dovecot[2997]: pop3(user2): Debug: Effective uid=100003, gid=100003, home=/_Data/Mailstores/100003 dovecot[2997]: pop3(user2): Debug: Home dir not found: /_Data/Mailstores/100003 dovecot[2997]: pop3(user2): Debug: fs: root=/_Data/Mailstores/100003/mboxes, index=, control=, inbox=/_Data/Mailstores/100003/mboxes/inbox, alt= dovecot[2997]: pop3(user2): Debug: Namespace : /_Data/Mailstores/100003/mboxes doesn't exist yet, using default permissions dovecot[2997]: pop3(user2): Debug: Namespace : Using permissions from /_Data/Mailstores/100003/mboxes: mode=0700 gid=-1 dovecot[2997]: pop3(user2): Debug: Namespace : /_Data/Mailstores/100003/mboxes/inbox doesn't exist yet, using default permissions dovecot[2997]: pop3(user2): Debug: Namespace : Using permissions from /_Data/Mailstores/100003/mboxes: mode=0700 gid=-1 dovecot[2997]: pop3(user2): Debug: Namespace : /_Data/Mailstores/100003/mboxes/inbox doesn't exist yet, using default permissions dovecot[2997]: pop3(user2): Debug: Namespace : Using permissions from /_Data/Mailstores/100003/mboxes: mode=0700 gid=-1 while "doveadm who" pretends nobody is connected: username # proto (pids) (ips) To get rid of the pop3 process, I have to send it a KILL signal: no other way. But this is noticed by the master process: dovecot[2997]: pop3(user2): Fatal: master: service(pop3): child 3113 killed with signal 9 Note that it is possible to connect afterwards as user2 through imap. On the other hand, trying to connect as user1 or user2 through pop always hangs. TIA, Axel

[Dovecot] dsync: Invalid server handshake
by Dusan Zivadinovic 08 Feb '13

08 Feb '13

Hi list, I recently tried to backup mailboxes from an older server machine to a new one in order to move the service to the new machine. Both machines are in the same LAN, I used this command: dsync -R -u username backup ssh -i .ssh/id_rsa username(a)192.168.1.11 /opt/local/bin/dsync and I get this error: dsync-local(dz): Error: Invalid server handshake: dsync-server 2 dsync-remote(dz): Error: Invalid client handshake: dsync-client 1 # lokal machine: dovecot 2.0.19apple1 running on Mac OS X 10.8.2 Server using standard Apple-Dovecot-Configuration # remote machine: 2.1.12 running on Mac OS X 10.4 using PAM authentication I cant seem to find any documentation to this error, nor do I find any dsync entries in the logs of both machines. Does anyone have a hint? Thank you, Dusan

[Dovecot] File permissions used for automatically created mailbox
by Frerich Raabe 07 Feb '13

07 Feb '13

Hi, I'm running Dovecot 2.1.12 on FreeBSD (quite successfully so, thanks for this nice piece of software!). One thing which is slightly annoying though is that automatically created mailboxes (I have lda_mailbox_autocreate set) don't have the file permissions I'd like them to have. I'm using a vmail-based system, i.e. all mail is owned by vmail:vmail; another member of the vmail group is called 'backup', which has read access to all mail in order to create backups. All mail is stored beneath /home/vmail, e.g. /home/vmail/frerich/Maildir Right now, newly created mailbox directories (e.g. /home/vmail/bob) have 0700 permissions, but I'd like to have 0750 for all directories and 0640 for all files so that all files and directories are group-readable for backup purposes. Does anybody know whether this is configurable somehow? Right now, my workaround consists running this cron script every night: #!/bin/sh chown -R vmail:vmail /home/vmail/ find /home/vmail/ -type d -print0 | xargs -0 chmod 0750 find /home/vmail/ -type f -print0 | xargs -0 chmod 0640 -- Frerich Raabe - raabe(a)froglogic.com www.froglogic.com - Multi-Platform GUI Testing

[Dovecot] Subfolders problem
by Adam Maciejewski 06 Feb '13

06 Feb '13

I have moved from dovecot 1.x to 2.x and I have big problem with subfolders. When I'm moving subfolder with other subfolders is moving only main subfolder, without subfolders, example : mail-storage-1 /var/vmail/home/adamskitest/mdbox/mailboxes # find | egrep -e "janusz|jarek" ./jarek ./jarek/dbox-Mails ./jarek/dbox-Mails/dovecot.index.log ./jarek/jarek2 ./jarek/jarek2/dbox-Mails ./jarek/jarek2/dbox-Mails/dovecot.index.log ./jarek/jarek2/jarek3 ./jarek/jarek2/jarek3/dbox-Mails ./jarek/jarek2/jarek3/dbox-Mails/dovecot.index.log ./janusz ./janusz/dbox-Mails ./janusz/dbox-Mails/dovecot.index.log ./janusz/janusz2 ./janusz/janusz2/dbox-Mails ./janusz/janusz2/dbox-Mails/dovecot.index.log ./janusz/janusz2/janusz3 ./janusz/janusz2/janusz3/dbox-Mails ./janusz/janusz2/janusz3/dbox-Mails/dovecot.index.log And now I'm moving jarek2 with jarek3 as subfolder to janusz2 subfolder, result : mail-storage-1 /var/vmail/home/adamskitest/mdbox/mailboxes # find | egrep -e "janusz|jarek" ./jarek ./jarek/dbox-Mails ./jarek/dbox-Mails/dovecot.index.log ./jarek/jarek2 ./jarek/jarek2/jarek3 ./jarek/jarek2/jarek3/dbox-Mails ./jarek/jarek2/jarek3/dbox-Mails/dovecot.index.log ./janusz ./janusz/dbox-Mails ./janusz/dbox-Mails/dovecot.index.log ./janusz/janusz2 ./janusz/janusz2/dbox-Mails ./janusz/janusz2/dbox-Mails/dovecot.index.log ./janusz/janusz2/dbox-Mails/dovecot.index.cache ./janusz/janusz2/janusz3 ./janusz/janusz2/janusz3/dbox-Mails ./janusz/janusz2/janusz3/dbox-Mails/dovecot.index.log ./janusz/janusz2/jarek2 ./janusz/janusz2/jarek2/dbox-Mails ./janusz/janusz2/jarek2/dbox-Mails/dovecot.index.log As You can see there is jarek2 subfolder but jarek3 havent been moved. I can see this folder in Thunderbird, after clicking error message pops out saying folder dosent exist. -- Adam Maciejewski

Greetings, A probably simple question and answer: can a sieve script be executed on outgoing messages? I already use deliver on postfix, perhaps the sieve script could be executed when saving to the Sent folder? Regards, -- Marcio Merlone

by Radek Novotný 06 Feb '13

06 Feb '13

Hi all, let me ask a question, please. Is it possible in dovecot to set up per user special-use folder names? Imagine situation with two users where first prefere another language that second. mailbox Sent { special_use = \Sent } for english speaking users and mailbox "Odeslaná pošta" { special_use = \Sent } for czech speaking users. Thanks for your answers. Radek
