[Dovecot] Dovecot pop3 segfault problems
by enid vx 24 Sep '10

24 Sep '10

Hi to all, I have a Debian 4.0 x86_64 server and installed Dovecot from the repositories ii dovecot-common 1.0.rc15-2etch5 ii dovecot-imapd 1.0.rc15-2etch5 ii dovecot-pop3d 1.0.rc15-2etch5 Recently I'm getting a lot of these messages pop3[24594]: segfault at 0000000000000004 rip 000000000044333a rsp 00007fffc5d0c1e0 error 4 in syslog and also dmesg. Also the load of the servers keeps increasing (like above 100) and when dovecot is stopped the load decreases. What problem could this be and how can I resolve it? Thanks, Enid

[Dovecot] dovecot+sieve redirect action signal 11 while user homedir not defined
by Maciej Uhlig 24 Sep '10

24 Sep '10

Hi, while executing simple sieve script: require ["fileinto", "envelope"]; if header :contains "subject" "test" { redirect "user@domain"; } we got: 2010-09-23T09:25:23+02:00 st1/192.168.10.201 dovecot: [ID 583609 mail.error] master: Error: service(lmtp): child 15524 killed with signal 11 (core not dumped) in case user home directory is (erroneously) undefined. This happens with 'redirect' action only ('keep', 'fileinto' work ok). Moreover, since there is no homedir, there is no core file too :-) After user homedir was defined, the error disappeared. This is under Solaris 10 with dovecot 2.0.3 and pigeonhole 0.2.0. Thank you, Maciej Uhlig

[Dovecot] Setting hierarchy separator
by ksrini9＠yahoo.com 24 Sep '10

24 Sep '10

I am trying to convert my maildir mail store to dbox using dsync (using "dsync -u username convert dbox:/mailstore2/dbox"). I get the following error message: dsync(root): Fatal: Mail locations must use the same virtual mailbox hierarchy separator (specify separator for the default namespace). My problem is that I do not know how to set separator in 10-mail.conf. I would appreciate any pointers. Here is the output from dovecot -n: # 2.0.3: /usr/local/etc/dovecot/dovecot.conf # OS: Linux 2.6.18-194.el5 x86_64 Red Hat Enterprise Linux Server release 5.5 (Tikanga) ext3 auth_cache_size = 20480 auth_cache_ttl = 7200 s base_dir = /var/run/dovecot/ disable_plaintext_auth = no listen = * log_path = /var/log/dovecot.log mail_location = maildir:/mailstore/dovecot/maildir/%u maildir_very_dirty_syncs = yes passdb { args = /etc/passwd.dovecot driver = passwd-file } postmaster_address = postmaster@localhost protocols = imap service imap-login { inet_listener imap { port = 143 } service_count = 0 vsz_limit = 67108864 } ssl = no userdb { driver = passwd } Thanks, Srini

[Dovecot] Upgrading from 2.0.1 to 2.0.3
by Jerrale G 24 Sep '10

24 Sep '10

What has changed in 2.0.3 to make dovecot start storing the inbox in a "com" subdirectory of "user@domain"directory in the inbox folder? I am guessing I need to add ":INBOX=/home/mail/%d/%n/mail/" to: mail_location = maildir:/home/mail/%d/%n/mail:CONTROL=/home/mail/control/%d/%n:INDEX=/home/mail/index/%d/%n The inbox was never defined as it automatically put the messages in either "cur" or "new" subdirectories of the "maildir" definition. Because it automatically used subdirectories, it was not a problem for it to use the "maildir" as both the Inbox directory and the directory to hold the other directories created by the user; so, I never defined the inbox. The mysql query is: user_query = SELECT CONCAT('/home/mail/', mailboxes.domain, '/', mailboxes.username, '/') AS home, CONCAT('/home/mail/', mailboxes.domain, '/', mailboxes.username, '/sieve/', mailboxes.username, '.sieve') as sieve, CONCAT('/home/mail/', mailboxes.domain, '/', mailboxes.username, '/sieve/') as sieve_dir, CONCAT('/home/mail/', mailboxes.domain, '/', mailboxes.username, '/mail/') AS maildir, 600 AS uid, 600 AS gid, CONCAT('*:storage=', ROUND(mailboxes.quota/1200), 'M') AS quota_rule, 'Trash:ignore' AS quota_rule2 FROM mail.mailboxes WHERE username = '%n' AND domain = '%d' AND active = '1' iterate_query = SELECT concat(mailboxes.username, '@', mailboxes.domain) AS user, CONCAT('/home/mail/', mailboxes.domain, '/', mailboxes.username, '/') AS home, CONCAT('/home/mail/', mailboxes.domain, '/', mailboxes.username, '/mail/') AS maildir FROM mail.mailboxes I was looking at another thread and saw where the names of dovecot fields, such as "userdb_maildir", have been prefixed with userdb to equal "userdb_maildir". Please Let me know of any changes, or additions, I need to do above. As said, I'm guessing I need to just add ":INBOX=/home/maill/%d/%n/mail/" to dovecot.conf or add ", CONCAT('/home/mail', mailboxes.domain, '/', mailboxex.username, '/mail/') AS INBOX" to the mysql query. Am I correct? Thanks Jerrale G. SC Senior Admin

[Dovecot] Does Director only work with dovecot proxy?
by Edward Carraro 23 Sep '10

23 Sep '10

I was reading "conf.d/10-director.conf" and it mentions Dovecot proxy. I've been using perdition in the past for my pop/imap proxying needs and wasn't sure if Director could also use perdition or if it only works with Dovecots proxying. Thanks!

[Dovecot] Creating 'trash' folder
by Jerry 23 Sep '10

23 Sep '10

This might well be OT; however, I thought I would ask anyway. Please keep in mind that the IMAP server is Dovecot. I have a friend who uses Becky Internet Mail <http://www.rimarts.co.jp/becky.htm> on a Windows system. There us an options under the configuration menu in Becky to create the trash folder on the server. It suggest ".trash" for the name. He is aware that I use Dovecot and wanted to know if that would actually work. He claims to have activated that option in Becky; however, the trash folder was never actually created, or at least he was unable to locate it. I was just wondering if anyone had any experience with this sort of thing. I could gather more information, but I doubt that this really has anything to do with Dovecot anyway. -- Jerry ✌ Dovecot.user(a)seibercom.net Disclaimer: off-list followups get on-list replies or get ignored.

[Dovecot] Plain-Text & CRAM-MD5
by Leander S. 23 Sep '10

23 Sep '10

Hi there, I'm currently running my auth against CRAM-MD5 only. But I face problems with customers who apparently have smart phones which ONLY support plain-text authentification ;( Bad - I know, but what should I do ... ;/ So my question now is: Is it possible to run CRAM-MD5 as well as Plain-Text auth together with Postfix if Postfix is using Dovecot's SASL auth service? Cause that's how my setup currently looks like - except the plain-text auth ... Thanks & Regards

[Dovecot] recursive locks
by Mike Abbott 23 Sep '10

23 Sep '10

How can a dovecot-2 plugin safely use file-locks or file-dotlocks when the processes into which it plugs handle multiple connections? (Via, e.g., service imap { client_limit = N service_count = 0 }) Dovecot's file-locks and file-dotlocks do not appear to support nesting/recursion. For instance, squat_trie_lock(). Imagine one user is connected to a single imap process twice.
