[Dovecot] Big problems after upgrade from beta8 (FC5) to rc21
by Jim Garrison 06 Feb '07

06 Feb '07

After upgrading a working system from FC5's beta8 to rc21, one vhost is failing with: > dovecot: Feb 05 09:54:30 Error: POP3(user(a)mydomain.com): > open(/var/mail/vhosts/mydomain.com/david/user, O_CREAT) failed: Not a > directory > dovecot: Feb 05 09:54:30 Error: POP3(user(a)mydomain.com): > mkdir_parents(/var/mail/vhosts/mydomain.com/user/.imap/INBOX) failed: > Not a directory > dovecot: Feb 05 09:54:30 Error: POP3(user(a)mydomain.com): Couldn't open > INBOX: Internal error occurred.

If so, how do I recover so users can retrieve mail again? Thx.

[Dovecot] LDAP auth_bind=yes in rc21 = goodness
by Adrian Close 06 Feb '07

06 Feb '07

Hi all, I finally got a chance to try out the fix for the LDAP auth_bind=yes issues in production (using rc21). It seems to be working just fine even after 24 hours of severe abuse. Incidentally, I had switched to bsdauth+login_ldap (on OpenBSD) which was often OK, but occasionally I would see Postfix smtpd throttled with SASL errors due to "connection refused" on the Dovecot authentication socket. This may just have been due to increased LDAP server load (Dovecot's internal LDAP generates much less). Thanks Timo! (And thanks Brad for updating the port) Adrian.

[Dovecot] minor kerberized dovecot build issue
by Dan Price 05 Feb '07

05 Feb '07

Hi all, again, I'm not knowledgeable about Kerberos, but we have a few users who use it to make sure that it works well on Solaris... so, they would like a Kerberized IMAPd. I tried compiling dovecot --with-gssapi on Solaris Nevada (the current development release), and the configure script choked for a couple of reasons. First, script uses 'grep -qv' in the case that you specify --with-gssapi to run some test. Unfortunately, Solaris doesn't have 'grep -q'. There's a note in GNU grep's manpage about this problem and a note that portable scripts should just redirect to /dev/null. Once I fixed this problem, I got: configure: WARNING: gssapi/gssapi.h: present but cannot be compiled configure: WARNING: gssapi/gssapi.h: check for missing prerequisite headers? configure: WARNING: gssapi/gssapi.h: see the Autoconf documentation configure: WARNING: gssapi/gssapi.h: section "Present But Cannot Be +Compiled" configure: WARNING: gssapi/gssapi.h: proceeding with the preprocessor's result configure: WARNING: gssapi/gssapi.h: in the future, the compiler will take +precedence configure: WARNING: ## ---------------------------------- ## configure: WARNING: ## Report this to dovecot(a)dovecot.org ## configure: WARNING: ## ---------------------------------- ## For whatever reason, on Solaris /usr/bin/krb5-config does not like the syntax 'krb5-config --cflags gssapi' (ditto with --libs). I found that removing the 'gssapi' part from the configure script fixed the problem, but I imagine this must break some other OS. If need be, I can follow up with the Kerberos team about this. Once I made these minor changes, I also had to add -lgss to the src/auth makefile's compile line. After that, I had no problem getting this to compile, although we have not yet tested it. -dp -- Daniel Price - Solaris Kernel Engineering - dp(a)eng.sun.com - blogs.sun.com/dp

[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] 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
