[Dovecot] Compile without GSSAPI disables SSL?
by Troy Engel 05 Feb '07

05 Feb '07

Perchance this is something unique to Red Hat -- I'm compiling/running 1.0rc?? on a CentOS 4 machine (i386), building RPMs and trimming down things I don't need (SQL e.g.). If I compile with the flag --with-gssapi, the resulting dovecot-auth binary links to libcrypto and libssl, the standard OpenSSL libs. Life is happy even though I don't need gssapi/krb5 support. If I remove --with-gssapi (but leave --with-ssl=openssl as before), the resulting dovecot-auth binary is no longer linked to the OpenSSL libraries (so I'm assuming no TLS/SSL support, but can't run the binary to test - I have SSL betatest users). So the question is, is this a ./configure problem in Dovecot, or some strangeness with Red Hat that you must link with gssapi/krb5 to get OpenSSL? Anyone care to hazard a guess? -te == details == The full configure line generated by the build is: + ./configure --build=i686-redhat-linux-gnu --host=i686-redhat-linux-gnu --target=i386-redhat-linux-gnu --program-prefix= --prefix=/usr --exec-prefix=/usr --bindir=/usr/bin --sbindir=/usr/sbin --sysconfdir=/etc --datadir=/usr/share --includedir=/usr/include --libdir=/usr/lib --libexecdir=/usr/libexec --localstatedir=/var --sharedstatedir=/usr/com --mandir=/usr/share/man --infodir=/usr/share/info 'INSTALL_DATA=install -c -p -m644' --with-doc --with-ssl=openssl --with-ssldir=/etc/pki/dovecot --with-ldap --with-gssapi --with-linux-quota=2 With gssapi: Install prefix ...................... : /usr File offsets ........................ : 64bit I/O loop method ..................... : poll File change notification method ..... : dnotify Building with SSL support ........... : yes (OpenSSL) Building with IPv6 support .......... : yes Building with pop3 server ........... : yes Building with mail delivery agent .. : yes Building with GSSAPI support ........ : yes Building with user database modules . : static prefetch passwd passwd-file checkpassword (modules) Building with password lookup modules : passwd passwd-file shadow pam checkpassword (modules) Building with SQL drivers ............: Without gssapi: Install prefix ...................... : /usr File offsets ........................ : 64bit I/O loop method ..................... : poll File change notification method ..... : dnotify Building with SSL support ........... : yes (OpenSSL) Building with IPv6 support .......... : yes Building with pop3 server ........... : yes Building with mail delivery agent .. : yes Building with GSSAPI support ........ : no Building with user database modules . : static prefetch passwd passwd-file checkpassword (modules) Building with password lookup modules : passwd passwd-file shadow pam checkpassword (modules) Building with SQL drivers ............: -- Troy Engel | Systems Engineer Fluid, Inc | http://www.fluid.com

[Dovecot] URGENT: specify mailboc location
by T. Horsnell 05 Feb '07

05 Feb '07

Is there a way I can tell dovecot to only use the .subscriptions file, if it exists, as the source of mailfolder paths, rather than have it look at every file in a user's directory to see if it's a mail folder? I'm on RHEL4, still on dovecot dovecot-0.99.11 Thanks, Terry.

by Charlie Root 05 Feb '07

[Dovecot] a namespace "mbox" without an INBOX
by David Bonnafous 05 Feb '07

05 Feb '07

hi, (dovecot 1.0r15) I try to setup up two namespaces: 1- the first one (and default one) a maildir namespace 2- the second one a mbox namespace I want only one "INBOX", in the maildir namespace, no INBOX in the mbox namespace. I get what I want with this configuration: ---------------------------------------- mail_location = maildir:~/Maildir namespace private { inbox = yes } namespace private { separator = . prefix = mbox. location = mbox:~/mbox:INBOX= inbox = no hidden = no } ---------------------------------------- My question is: is it a normal way to do what I want ? I mean, the line location = mbox:~/mbox:INBOX= looks odd. I try with just the line inbox=no (without INBOX=) but dovecot set a default INBOX that disturbs some mail client. yours, -- David Bonnafous Institut de Mathématiques Université Paul Sabatier Toulouse - France

[Dovecot] Large & busy site, NFS with deliver only servers
by Dean Manners 05 Feb '07

05 Feb '07

Timo / Others, I have been working on a new installation for a fairly busy site, and after many weeks of tribulation have come to an architecture Im happy with: 2x Debian (2.6.18) - MXing machines running Postfix / MailScanner / Dovecot-LDA (A slightly patched RC17 for prettier Quota bounces) 2x Debian (2.6.18) - Mail retrieval machines running Dovecot IMAP/POP3 (Currently RC17) 3x Node Isilon NFS cluster (NetApp type devices) I chose Dovecot-LDA over Postfix-Virtual / Maildrop / Procmail due to its hassle free auto creation of new user maildirs, and the funkyness of built in Sieve functionality. The on the fly indexing sounded like a bonus at the time. However as Im sure all people who stress test with index's stored over NFS find, index locking makes for some 'spectacular crashes' (see others previous posts). I have tried out the recommended mount options and locking methods to no avail. Once under some stress, say ~60 messages a minute from the two front end machines, understandably the index's get pickled instantly. So as a hack way around the index locking problems, I have configured the MXing machines to index locally to no where (/tmp) - and deal with the very slightly slower IMAP/POP3 performance on the retrieval side. Is there way to tell/patch Dovecot-LDA not to bother with indexing? So Im not creating unused index files. Cheers __________________________________________ Dean Manners

[Dovecot] Quota crashing w/ gdb backtrace

Hi, I'm still running into consistent crashing when moving files between folders when dirsize quotas are enabled. This is running Dovecot1.0rc19.

However, the original files never gets deleted, so I assume that this crash is occuring during the deletion in the original folder. -- Dean Brooks dean(a)iglou.com

[Dovecot] broken attachments with pop3
by Robert Schetterer 05 Feb '07

05 Feb '07

Hi all, ive just upgrade to rc21 ( so i dont know perhaps this report failure is fixed with this release ) i have reports from users that attachments get broken ( with rc19, dont know about before ) with some accounts , which where downloaded via a pop3 service to a exchange server, but in fact nothing is broken when looking with imap to the mailboxes Has anyone an idea, i havent any failure logs about that, is there a parameter which makes logging verbose to such failures? -- Mit freundlichen Gruessen Best Regards Robert Schetterer https://www.schetterer.org Munich/Bavaria/Germany -- Diese Nachricht wurde auf Viren und andere gefährliche Inhalte untersucht und ist - aktuelle Virenscanner vorausgesetzt - sauber.

[Dovecot] SSL error is it due to a self certified certificate?
by Matthew Bickerton 05 Feb '07

05 Feb '07

Hi I have set up dovecot with a self signed SSL certificate, created with the mkcert.sh script. Now I see the following in the log: pop3-login: SSL_accept() failed: error:14094416:SSL routines:SSL3_READ_BYTES:sslv3 alert certificate unknown [206.124.112.22] pop3-login: Disconnected: rip=206.124.112.22, lip=204.3.153.71, TLS handshake Is this caused by my self certified certificates. Or is it another problem? Thanks Matthew

[Dovecot] mail_log plugin, log throttling and killing of the IMAP child.
by Tan Shao Yi 05 Feb '07

05 Feb '07

Hi, Just a quick check, was wondering if anyone is experiencing problems mass deleting/purging mails from a folder? I am on RC19 with the mail_log plugin enabled. Quite often, when a mass deletion/purge is attempted, we receive the following message in the dovecot logs: dovecot: Feb 01 11:36:27 Error: IMAP(userid): Sending log messages too fast, throttling.. Sometimes this is accompanied by a message like the following and the user will be prompted with an error message saying that the connection has been abruptly terminated. dovecot: Feb 01 11:34:41 Error: child 3908 (imap) killed with signal 11 Is anyone experencing similar behaviour? Cheers, Tan Shao Yi

05 Feb '07

The following shows up in the "orphaned page" list of the Wiki: http://wiki.dovecot.org/MboxLocking?action=show&redirect=MboxSoftwareLocks Does the description of Dovecot mbox locking still apply to current versions? If yes, it should be linked from the "Troubleshooting" page. -- Jim Garrison (jhg(a)acm.org) PGP Keys at http://www.jhmg.net RSA 0x04B73B7F DH 0x70738D88
