[Dovecot] Problems enabling quota on MacOS X
by Lars Skovgaard 05 Feb '07

05 Feb '07

Hi, I'm trying to activate quotas for my users, preferably maildir++ quotas as all users are using maildir. I have compiled dovecot with quota-support, but when I try to enable quotas in the config, dovecot refuses to start up with a (to me, at least) strange message: Fopendir(/usr/local/lib/dovecot/imap) failed: No such file or directory Error: imap dump-capability process returned 89 In the logs I get the following: dovecot: read (imap dump-capability process) failed: Interrupted system call The directory "/usr/local/lib/dovecot/imap" is not missing, which would be the obvious explanation... Dovecot-version is 1.0rc21 (which by the way is running ***great*** without quotas). Thanks, /Lars

[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.

[Dovecot] pop3 not working properly in 1.0.r19

[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] 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
