[Dovecot] 1.1.6 -> 1.1.7 regression: dovecot: pipe() failed: Too many open files
by Mark Zealey 12 Jan '09

12 Jan '09

Hi all, We updated to 1.1.7 a week or two back from 1.1.6 (both standard atrpms builds). Since doing so, twice now I've seen the imap services accept connections but they hang before the banner is printed (pop seems to be unaffected). I see this in the logs: Dec 23 14:02:15 mail9 dovecot: pipe() failed: Too many open files Dec 23 14:02:15 mail9 dovecot: Temporary failure in creating login processes, slowing down for now Dec 23 14:02:15 mail9 dovecot: Created login processes successfully, unstalling Dec 23 14:02:16 mail9 dovecot: pipe() failed: Too many open files Dec 23 14:02:16 mail9 dovecot: Temporary failure in creating login processes, slowing down for now Dec 23 14:02:16 mail9 dovecot: Created login processes successfully, unstalling The ulimit for the number of open files on these servers has remained unchanged at 8192 and there are no warnings about too few fd's on dovecot startup. There weren't amazing numbers of imap sessions open at the time (only something like 400-500; we've had 1.5k in the past), so I suspect this is a regression between 1.1.6 and 1.1.7 where you've got a leak of fd's ? If it happens again I'll try and get a snapshot of the fd's open by the master dovecot process.

[Dovecot] download IMAP folders via POP3
by Jakob Grießmann 11 Jan '09

11 Jan '09

Hi, I know my question might sound a little bit strange, but is it possible to download IMAP folders via POP3? I have clients who use POP3 on their main machines and IMAP on their "on the road" notebooks. It would be good to download all folders created on the notebook via POP3 to the main desktop. Googling brought up some results, but I don't know how to implement... Thanks Jakob

[Dovecot] TLS timeout with 1.2a4
by Luigi Rosa 09 Jan '09

09 Jan '09

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 I have a mail server CentOS 64bit (4 Gb RAM) with Dovecot 1.2a4 and three accounts. I use Thunderbird 2. If I enable SSL connection in Thunderbird 2, after three-five minutes I got a lot of different errors in Thunderbird (Server is not IMAP, Connection lost...). Everything comes back to normal if I restart Dovecot in the server, but after 5 minutes I got the same errors. This happens both with an ADSL connection (Thunderbird on Windows XP) AND with a direct 1 Gbit cross cable connection (Thunderbird on Ubuntu 64 8.10). If I disable SSL connection on Thunderbird, everything comes back to normal and I don't get any error. The SSL-related options in dovecot.conf are: ssl_disable = no ssl_cert_file = /etc/ssl/certs/dovecot.pem ssl_key_file = /etc/ssl/private/dovecot.pem ssl_parameters_regenerate = 47 verbose_ssl = yes ssl_cipher_list = ALL:!LOW disable_plaintext_auth = no What kind of logging can I enable to trace this error? On the logfile I find something like taht (there are only 3 seconds between the first and the last line) dovecot: imap-login: Login: user=<lists(a)aaa.com>, method=CRAM-MD5, rip=xxx, lip=yyy, TLS dovecot: imap-login: Login: user=<lists(a)aaa.com>, method=CRAM-MD5, rip=xxx, lip=yyy, TLS dovecot: imap-login: Disconnected: Shutting down (auth failed, 1 attempts): method=CRAM-MD5, rip=xxx, lip=yyy, TLS dovecot: imap-login: Disconnected: Shutting down (no auth attempts): rip=xxx, lip=yyy, TLS dovecot: imap-login: Disconnected: Shutting down (no auth attempts): rip=xxx, lip=yyy, TLS handshaking dovecot: imap-login: Disconnected: Shutting down (no auth attempts): rip=xxx, lip=yyy, TLS dovecot: imap-login: Disconnected: Shutting down (no auth attempts): rip=xxx, lip=yyy, TLS dovecot: imap-login: Disconnected: Shutting down (no auth attempts): rip=xxx, lip=yyy, TLS dovecot: imap-login: Disconnected: Shutting down (auth failed, 1 attempts): method=CRAM-MD5, rip=xxx, lip=yyy, TLS dovecot: imap-login: Disconnected: Shutting down (no auth attempts): rip=xxx, lip=yyy, TLS handshaking dovecot: imap-login: Disconnected: Shutting down (no auth attempts): rip=xxx, lip=yyy, TLS dovecot: imap-login: Disconnected: Shutting down (auth failed, 1 attempts): method=CRAM-MD5, rip=xxx, lip=yyy, TLS dovecot: imap-login: Disconnected: Shutting down (auth failed, 1 attempts): method=CRAM-MD5, rip=xxx, lip=yyy, TLS dovecot: imap-login: Disconnected: Shutting down (auth failed, 1 attempts): method=CRAM-MD5, rip=xxx, lip=yyy, TLS dovecot: imap-login: Disconnected: Shutting down (no auth attempts): rip=xxx, lip=yyy, TLS dovecot: IMAP(lrosa(a)bbb.com): Disconnected: Logged out bytes=1028/49877 dovecot: IMAP(lrosa(a)bbb.com): Disconnected: Logged out bytes=2253/49352 dovecot: IMAP(lrosa(a)bbb.com): Connection closed bytes=20466/553071 dovecot: IMAP(lrosa(a)bbb.com): Connection closed bytes=19417/163412 dovecot: IMAP(lrosa(a)bbb.com): Disconnected: Logged out bytes=2937/69241 dovecot: imap-login: Login: user=<lrosa(a)bbb.com>, method=CRAM-MD5, rip=xxx, lip=yyy dovecot: imap-login: Login: user=<lists(a)aaa.com>, method=CRAM-MD5, rip=xxx, lip=yyy, TLS dovecot: imap-login: Login: user=<lrosa(a)bbb.com>, method=CRAM-MD5, rip=xxx, lip=yyy dovecot: imap-login: Login: user=<lrosa(a)bbb.com>, method=CRAM-MD5, rip=xxx, lip=yyy dovecot: imap-login: Login: user=<lists(a)aaa.com>, method=CRAM-MD5, rip=xxx, lip=yyy, TLS dovecot: imap-login: Login: user=<lrosa(a)bbb.com>, method=CRAM-MD5, rip=xxx, lip=yyy dovecot: imap-login: Login: user=<lists(a)aaa.com>, method=CRAM-MD5, rip=xxx, lip=yyy, TLS dovecot: imap-login: Login: user=<lrosa(a)bbb.com>, method=CRAM-MD5, rip=xxx, lip=yyy dovecot: IMAP(lrosa(a)bbb.com): Connection closed bytes=205/41166 dovecot: IMAP(lrosa(a)bbb.com): Connection closed bytes=609/217506 dovecot: imap-login: Login: user=<lrosa(a)bbb.com>, method=CRAM-MD5, rip=xxx, lip=yyy Ciao, luigi - -- / +--[Luigi Rosa]-- \ Fallo oggi, domani potrebbe essere illegale. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.9 (GNU/Linux) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org iEYEARECAAYFAklBUKAACgkQ3kWu7Tfl6ZSQgwCbBoD6IEKjPNYriHrKmES4Zj+y ji0AnRZzU2ETJkVn72kmpR1C+cs3PNdf =T267 -----END PGP SIGNATURE-----

[Dovecot] Master user with "user="?
by Alan Ferrency 09 Jan '09

09 Jan '09

Hello, In our configuration, we are using a "passdb passwd-file", with "user=" directives in each username, and a separate "userdb passwd-file" which contains the target usernames for the "user=" directives. This works fine, for normal logins via POP and IMAP. For customer support testing purposes, we also set up a temporary "master=yes" passwd-file. This works fine, for any passdb username that does not have a "user=" field. However, it seems that if we use the master user to log into a username that is in the passdb with a "user=" field, dovecot looks in the userdb for the original username, and not for the "user=" username specified in the passdb passwd-file. Is this a known bug? Maybe I'm doing something wrong? Thanks! Alan Ferrency pair Networks, Inc. alan(a)pair.com

[Dovecot] Error: dict: Failed to initialize dictionary 'expire'
by LÉVAI Dániel 09 Jan '09

09 Jan '09

Hi! Using dovecot-1.1.17, and BDB-4.6.21. I'm having this error in every two weeks or so. I've running this in a crontab: /usr/local/sbin/dovecot --exec-mail \ ext /usr/local/libexec/dovecot/expire-tool The expire plugin and tool is working fine, the configuration is ok, and I'm using the BDB backend. What happens in every ~two weeks is dovecot starts to give me this error messages: Error: dict: db_env: Unable to allocate memory for transaction detail Error: dict: Failed to initialize dictionary 'expire' Reading thru Oracle's Berkeley DB FAQ: http://www.oracle.com/technology/products/berkeley-db/faq/db_faq.html#28 "This error means the maximum number of active transactions configured for Berkeley DB has been reached [...] When all of the memory available in the database environment for transactions is in use, calls to being a transaction will fail until some active transactions complete. By default, the database environment is configured to support at least 20 active transactions." What could be happening here? Why coudn't it finish its transactions? After a dovecot restart it works fine :\ Thanks in advance for any hints. Daniel -- LEVAI Daniel PGP key ID = 0x4AC0A4B1 Key fingerprint = D037 03B9 C12D D338 4412 2D83 1373 917A 4AC0 A4B1
