[Dovecot] pop/imap login logging only username part of full email address
by Justin McAleer 24 Jan '07

24 Jan '07

I have my login log format set like so: login_log_format_elements = user=<%u> method=%m rip=%r lip=%l %c When I log in using a full email address, though, I only get the username part of the address: Jan 24 13:28:29 node7 dovecot: pop3-login: Login: user=<justin>, method=PLAIN, rip=137.118.2.60, lip=137.118.7.247 Jan 24 13:28:30 node7 dovecot: POP3(justin): Disconnected: Logged out top=0/0, retr=0/0, del=0/717, size=15797460 Is that behavior intentional? If so, can it log the full username as given by the client instead? Anyone with multiple domains probably wants to see the domain part. Changing %u to %n yields the same log entry, and %d seems to be empty so nothing gets logged if I try to log that.

[Dovecot] More AFS maildir debugging
by Aaron Solochek 24 Jan '07

24 Jan '07

There appears to be some sort of a race condition when accessing a maildir directory for the first time with dovecot. I was getting a non-specific error trying to select INBOX, but when I stepped through it with a debugger it worked. Deleting the dovecot files and running the select again it failed. I started playing with it again just now, and when attempting to access Sent, I actually got some errors: a04 select Sent imap(aarons): Error: Corrupted transaction log file /XX/Maildir/.Sent/dovecot.index.log: unexpected end of file while reading header imap(aarons): Error: Corrupted transaction log file /XX/Maildir/.Sent/dovecot.index.log: unexpected end of file while reading header imap(aarons): Error: Corrupted transaction log file /XX/Maildir/.Sent/dovecot.index.log: unexpected end of file while reading header a04 NO Internal error occurred. Refer to server log for more information. [2007-01-13 16:17:51] I then deleted dovecot.index.log and dovecot.index.log.2 (the only two dovecot files that were present) and retried the select: a04 select Sent a04 NO Internal error occurred. Refer to server log for more information. [2007-01-13 16:23:40] Does anyone more familiar with the code than myself have any pointers of where to concentrate my debugging efforts? Thanks. -Aaron

[Dovecot] dovecot-acl file location in rc18
by Radek Zavicak 24 Jan '07

24 Jan '07

Hi, I'm trying to use ACL with dovecot rc18 but I don't understand where to store per-mailbox dovecot-acl file. In dovecot.conf I have mail_location = maildir:/var/vmail/%u/ and I do not use namespaces. I have some "testuser" maildir with subdir ".test". When I put dovecot-acl file to the .test directory I get this error in my log file: Error: IMAP(testuser): /var/vmail/testuser/.test/dovecot-acl is no longer kept in control directory, move it to the actual maildir (/var/vmail/testuser/.test) Error: child 28143 (imap) returned error 89 This error tells me to move dovecot-acl file from control dir to mail directory but these are the same for me (and I think it's Dovecot default for maildir). Where I should store per-mailbox dovecot-acl file in this case? Regards, Radek Zavicak

[Dovecot] too many open files error when using quota plugin
by Justin McAleer 24 Jan '07

24 Jan '07

With the quota plugin loaded (even with a quota value of 0), I get errors like the following: open(/var/mailstore/01/1a/301620/Maildir/cur/1169654988.P22440Q0M696852.<hostname stripped>,S=4437552:2,Sbc) failed: Too many open files To do this, I have a folder with about 700 messages and I tell Thunderbird to run junkmail controls on it (fetches all messages). Watching an strace on the imap process I'm connected to, the problem seems to be when the plugin goes to close the maildirsize file, it's not closing the correct file descriptor: open("/var/mailstore/01/1a/301620/Maildir/./maildirsize", O_RDWR|O_APPEND) = 1016 read(1016, "1024S\n395 1\n397 1\n", 5120) = 18 read(1016, "", 5102) = 0 close(4294967295) = -1 EBADF (Bad file descriptor) It closes that same descriptor every time. On a side note, I'm just curious why it needs to read the maildirsize file for a fetch request anyway?

[Dovecot] building with SSL support in non-std directories
by AJ Weber 24 Jan '07

24 Jan '07

I'm trying to get configure to find the right libs/includes to build with SSL support (openssl), but it just seems to refuse! I tried passing " --with-ssl=openssl --with-ssldir=/usr/local/ssl ", but this didn't seem to help. In /usr/local/ssl is: drwxr-xr-x 2 root root 4096 2006-12-11 13:25 bin drwxr-xr-x 2 root root 4096 2006-12-11 12:15 certs drwxr-xr-x 3 root root 4096 2006-12-11 12:15 include drwxr-xr-x 4 root root 4096 2006-12-11 13:25 lib drwxr-xr-x 6 root root 4096 2006-12-11 12:15 man drwxr-xr-x 2 root root 4096 2006-12-11 13:25 misc -rw-r--r-- 1 root root 9374 2006-12-11 13:25 openssl.cnf drwxr-xr-x 2 root root 4096 2006-12-11 12:15 private Can someone tell me what it's looking for and how to properly tell it to compile in the SSL support??? Thanks, AJ

[Dovecot] dovecotpw/sql crypt scheme core dump with rc17-19
by Andre Dalle 24 Jan '07

24 Jan '07

Platform is Solaris 8 on a 280R. I'm setting up a new installation of Dovecot, and I ran into some troubles that I've partly tracked down. I setup auth/user dbs with LDAP initially, and things worked well. Passwords are stored as "{crypt}zxcv..." in LDAP. I setup SQL, and began getting this: dovecot: Jan 23 16:37:47 Error: child 8718 (auth-worker) killed with signal 11 Passwords are stored as "zxcv..." in SQL. I changed default_pass_scheme from CRYPT to PLAIN, and no troubles. I then tried dovecotpw: dovecotpw -p 123 -s PLAIN-MD5 {PLAIN-MD5}202cb962ac59075b964b07152d234b70 dovecotpw -p 123 -s CRYPT Segmentation Fault (core dumped) So I then tried this: truss dovecotpw -p 123 -s crypt open64("/dev/urandom", O_RDONLY) = 3 read(3, "F80E82 c", 4) = 4 fcntl(3, F_GETFD, 0x00000000) = 0 fcntl(3, F_SETFD, 0x00000001) = 0 open64("/usr/local/lib/dovecot/auth/password", O_RDONLY|O_NDELAY) Err#2 ENOENT read(3, "8382", 2) = 2 Incurred fault #6, FLTBOUNDS %pc = 0xFF0E3304 siginfo: SIGSEGV SEGV_MAPERR addr=0x00000005 Received signal #11, SIGSEGV [default] siginfo: SIGSEGV SEGV_MAPERR addr=0x00000005 *** process killed *** Suffice to say, there is no "/usr/local/lib/dovecot/auth/password". I'm guessing that the dovecot auth-worker process is failing for the same reason but I don't know how to debug that one. I have core files for the dovecotpw process. -- André Dalle Systems Administrator NCF Internet

[Dovecot] All index file bugs fixed(?)
by Timo Sirainen 23 Jan '07

23 Jan '07

I fixed the nightly snapshot building. Now it's again being built every night (if there have been any changes). Please test it before I'll make rc18 release. http://dovecot.org/nightly/dovecot-latest.tar.gz I've also been stress testing a lot with http://dovecot.org/tools/imaptest.c. Last night I ran it for 9 hours with mmap_disable=yes and it picked up only one race condition, which is also now fixed. I'll run the next night with mmap_disable=no and see if anything shows up with it. I'm hopeful that there aren't any important index file related bugs left anymore. This is actually the first time in Dovecot's existence that I'm really not aware of *any* bugs in index file handling. v1.0 release should be really near now, unless you figure out new problems :) Here's a list of bugs that should have been fixed since rc17: "Corrupted index file dovecot.index: Record field keywords points outside record size (12 < 12+2)" "Corrupted Index file dovecot.index: Record [1].uid=0" Crashes - http://dovecot.org/list/dovecot-cvs/2007-January/007395.html "open() failed with file dovecot.index.log: No such file or directory" - http://dovecot.org/list/dovecot-cvs/2007-January/007405.html "Fixed index file dovecot.index: seen_messages_count 8 -> 9" "View synchronization from transaction log failed: Deleted counter wrong" etc. - http://dovecot.org/list/dovecot-cvs/2007-January/007403.html Corrupted transaction log errors: - http://dovecot.org/list/dovecot-cvs/2007-January/007389.html - http://dovecot.org/list/dovecot-cvs/2007-January/007393.html Corrupted view errors: - http://dovecot.org/list/dovecot-cvs/2007-January/007366.html - http://dovecot.org/list/dovecot-cvs/2007-January/007368.html Corrupted cache file errors: - http://dovecot.org/list/dovecot-cvs/2007-January/007364.html Fixed a lot of crashes whenever something went wrong (I deleted index files every 3 seconds until it crashed, last run went for several minutes before I stopped trying): - http://dovecot.org/list/dovecot-cvs/2007-January/007397.html

[Dovecot] 1.0.rc18 released
by Timo Sirainen 23 Jan '07

23 Jan '07

http://dovecot.org/releases/dovecot-1.0.rc18.tar.gz http://dovecot.org/releases/dovecot-1.0.rc18.tar.gz.sig I think we're quite near v1.0 now. * ACL plugin + Maildir: Moved dovecot-acl file from control directory to maildir. To prevent accidents caused by this change, Dovecot kills itself if it finds dovecot-acl file from the control directory. * When opening a maildir, check if tmp/'s atime is over 8h old. If it is, delete files in it with ctime older than 36h. However if atime - ctime > 36h, it means that there's nothing to be deleted and the scanning isn't done. We update atime ourself if filesystem is mounted with noatime. * base_dir doesn't need to be group-readable, don't force it. * mail_read_mmaped setting is deprecated and possibly broken. It's now removed from dovecot-example.conf, but it still works for now. * Removed also umask setting from dovecot-example.conf since currently it doesn't do what it's supposed to. + Authentication cache caches now also userdb data. + Added mail_log plugin to log various mail operations. Currently it logs mail copies, deletions, expunges and mailbox deletions. - dict quota: messages=n parameter actually changed storage limit. - A lot of fixes to handling index files. This should fix almost all of the problems ever reported. - LDAP: auth_bind=yes was more or less broken. - Saved mails and dovecot-keywords file didn't set the group from dovecot-shared file. - Fixed potential assert-crash while searching messages - Fixed some crashes with invalid X-UID headers in mboxes - If you didn't have a namespace with empty prefix, giving STATUS command for a non-existing namespace caused the connection to give "NO Unknown namespace" errors for all the future commands.
