[Dovecot] Dovecot, IMAP, and mutt
by Travis Poppe 09 Jun '06

09 Jun '06

Hello, I'm running FreeBSD 6.0 release on x86 hardware and am using mutt version 1.5.11. Not running dovecot on/over NFS or anything, just the standard UFS2 filesystem. I'm also using SSL for IMAP. Since dovecot 1.0.b8, I've had to instruct mutt to do things twice (such as deleting) before the changes will actually occur. I've confirmed that this does not happen with dovecot 1.0.b7, which is what I'm using now to work around the problem. To repeat, use mutt 1.5.11 in IMAP/SSL mode with dovecot 1.0.b8 and try to mark some mail for deletion. Then, press the '$' key to enact the changes. You'll see that the piece(s) of mail will still be there after doing so. Pressing the '$' key again will cause the mail to be removed. Any ideas as to what's going on? Thanks, -- Travis Poppe IRC: tlp @ irc.freenode.net

[Dovecot] Problem with dovecot-lda
by Jef Driesen 09 Jun '06

09 Jun '06

I have installed the dovecot 1.0 beta3 (package included with Ubuntu Dapper Drake) and everything is working very well. Next I wanted to try the dovecot lda (for sieve filtering). In postfix I have "mailbox_command = /usr/lib/dovecot/deliver" and I followed the instructions from http://wiki.dovecot.org/LDA. I only changed "postmaster_address = postmaster(a)localdomain.local" and "user = dovecot" from the example configuration. With this configuration, no mail is delivered (discarded?) and in the logfile there is this error: Jun 5 18:10:08 localhost postfix/local[9630]: BFA6D5A403: to=<jef(a)localdomain.local>, relay=local, delay=0, status=bounced (local configuration error. Command output: Fatal: open(/etc/dovecot/dovecot.conf) failed: Permission denied ) Changing permissions on /etc/dovecot/dovecot.conf to 644 fixes the problem, but I think this is not the best solution. Any ideas?

[Dovecot] Problem Compiling Dovecot-LDA
by Timothy White 09 Jun '06

09 Jun '06

I'm trying to setup Dovecot-LDA. I grab dovecot beta8 and compiled it with the following options. $ ./configure --without-deliver --with-mysql $ make # make install It builds fine, and I have it running fine now. I then tried to build dovecot-lda from cvs, with the following. $ ./configure --with-dovecot=../dovecot-1.0.beta8/ $ make and it then fails with the following gcc -std=gnu99 -g -O2 -Wall -W -Wmissing-prototypes -Wmissing-declarations -Wpointer-arith -Wchar-subscripts -Wformat=2 -Wbad-function-cast -o sievec sievec.o libsieve.a /home/tim/src/dovecot-1.0.beta8/src/lib/liblib.a libsieve.a(script.o)(.text+0xa23): In function `sieve_script_load': /home/tim/src/dovecot-lda/src/libsieve/script.c:435: undefined reference to `map_refresh' libsieve.a(script.o)(.text+0xaf0): In function `sieve_script_unload': /home/tim/src/dovecot-lda/src/libsieve/script.c:462: undefined reference to `map_free' libsieve.a(sieve.o)(.text+0x1e6e): In function `verify_flag': /home/tim/src/dovecot-lda/src/libsieve/sieve.y:951: undefined reference to `imparse_isatom' collect2: ld returned 1 exit status make[2]: *** [sievec] Error 1 make[2]: Leaving directory `/home/tim/src/dovecot-lda/src/libsieve' make[1]: *** [all-recursive] Error 1 make[1]: Leaving directory `/home/tim/src/dovecot-lda/src' make: *** [all-recursive] Error 1 Any ideas as to what is wrong? Grepping the src files for map_refresh, map_free, and imparse_isatom only show references in dovecot-lda, in src/imparse.c and src/map.c. It seems to be a problem with src/libsieve when trying to build the sieve stuff. But I'm not sure. Thanks Tim -- Linux Counter user #273956

[Dovecot] a bug in the LDAP code
by Udo Rader 08 Jun '06

08 Jun '06

Hi, I was heaving some grave problems with dovecot's ldap client that left me with the following settings for virtual users: -------CUT------- mbox: data=/virtual/oeush.at/home/f.someone/mail/:INBOX=/var/mail/f.someone.oeush.at -------CUT------- data in that case was correct, yet the INBOX location was wrong, this should have been /virtual/oeush.at/var/mail/f.someone.oeush.at instead. My settings for the retrieval of the mail environment in /etc/dovecot/dovecot-ldap.conf were like this: -------CUT------- user_attrs = homeDirectory=home,uidNumber=uid,gidNumber=gid,MailMessageStore=mail -------CUT------- now at first glance this seems correct, but the problem was the upper cased "MailMessageStore" attribute name. changing it to "mailMessageStore" gave me the correct settings: -------CUT------- mbox: data=/virtual/oeush.at/home/f.someone/mail/:INBOX=/virtual/oeush.at/var/mail/f.someone.oeush.at -------CUT------- I don't have any of the LDAP RFCs ready, but I think that per default the case of the attribute _names_ should not matter when querying an ldap server.

Hi, I have a login issue. I do everything I can think of, but can't login. My .conf file is at http://kabuto.kunduz.org/dovecot.conf and I make slight changes everytime I try a new thing. I last set disable_plaintext_auth to yes and when I try to login using Thunderbird, I get *Code:* Sending of username did not succeed. Mail server mail.somedomain.org responded: Plaintext authentication disabled. , and dovecot.log reads *Code:* Info: pop3-login: Login failed: Plaintext authentication disabled: method=PLAIN, rip=212.98.201.1, lip=192.168.1.2.

Marc Perkel scribbled: > Repeat after me - think outside the box. Did you miss the part where I said we've already tried this? Not only have we thought outside the box, but we've smashed it up and built several alternatives to see which one sucked the least. Turns out, SQL backends suck the most. Please try to keep up :) Marc Perkel also scribbled: > To do this with MySQL would be trivial. To do it without a database > isn't possible. Actually you could do that with a tiny Sieve extension. I don't think you really understand what you are even proposing. Your statement would be better phrased "to do it without an index would be slow". If you wanted to create a database server for mail, with a mail-specific query language, then that database might be called "Dovecot", and the query language might be called "IMAP". Innovation is not an excuse for lousy engineering. As usual, it turns out to be bad design practice to say "let's deploy shinytoy for feature X!" rather than say "we need capability X! What's a creative way to achieve that?". Which is why necessity is the mother of invention. /JG

People who optimise their systems for shiny cute features rather than the common case get all the hacks they deserve. Repeat after me: design for the common case. Also your proposed sql above and implications (arbitrary operations based on mail metadata i.e. headers) seems to involve indexing every mail header on delivery. Good luck with that one large scale mail storage. Did you want a mail database, or an OLAP system? >-) /jg
