Thanks but for mbox it is ".subscriptions", "subscriptions" is for maildir, but I found the BUG !!! ~/mail/.subscriptions is on an NFS mounted filesystem, it keeps on getting deleted... does not like NFS (the files are renamed .nfsXXXXX when deleted) if I patch the code to get it on a local filesystem, like my indexes (in storage->index_dir instead of storage->dir): /var/indexes/%u/.subscriptions then it stays alive and work.

[Dovecot] Clash between multiple authentication databases (security problem?)
by dovecot-ri 27 Mar '06

27 Mar '06

Hi all, I just installed dovecot-1.0_beta2 and love it! However, I've run into issues using multiple authentication databases. I use both pam (for users on my system) and sql (for virtual users). I've noticed that if I have system user "userabc" and virtual user "userabc(a)otherdomain.com" (two distinct users) and my "auth default" section contains these passdb/userdb entries in this order (the order in the example config): passdb pam passdb sql userdb pam userdb sql then when userabc(a)otherdomain.com logs in, he'll get the system user userabc's mail instead of his own. It appears that the sql password check succeeds, then Dovecot grabs the home directory from pam, NOT sql. I can work around this by setting up "userdb prefetch" and adding that section *before* "userdb pam". If I put "userdb prefetch" after "userdb pam" or after "userdb sql", then Dovecot doesn't actually do the prefetch (which causes an error since Dovecot issues the default SQL query for "user_query", which my MySQL database doesn't like). Is there a safer way to do this? If not, should there be? Thanks!

Going CVS, can we build and install dovecot-lda and keep the dovecot executable the way it is? Or do we have to rebuild the dovecot executable from the CVS tree too? Thank you. Marilyn Davis

[Dovecot] Some moved or copied messages get stuck in tmp
by Luis Meléndez 26 Mar '06

26 Mar '06

Hello. I have seen in recent posts that there are other people with this problem, and it is very important for me, as it is the only cause for not putting Dovecot in production in all mail servers in my University. When moving/copying messages, some of them get stuck in the tmp directory of the destination folder, effectively lost for the user. I have been tracing the problem, and it looks that it happens with messages that have flags. The others don't have problems. But if I copy/move several flagged messages, one of them is copied, and the others are kept in tmp. In maildir-save.c there is the following comment: /* if we have flags, we'll move it to cur/ directly, because files in new/ directory can't have flags. alternative would be to write it in new/ and set the flags dirty in index file, but in that case external MUAs would see wrong flags. */ that looks like a clue. It happens with CVS versions 20060320 and 20060325 I hace done almost all tests with Thunderbird.

[Dovecot] OS X-centricities? Too many files, temp, indexes, etc...
by Dean Blackburn 25 Mar '06

25 Mar '06

I'm just writing to see if anyone else is seeing the following issues, and particularly if they are running OS X (especially 10.4), and/or have compatible solutions (I've been reading the mailing list quite a bit, and every now and then, I find a solution that just "doesn't work" because of the differences in OS: 1) Too many files open - no plimit command on OS X, so I can't figure out how to increase the max number of open files... Also, are there any alternative means of CLOSING the files? stopping/restarting dovecot didn't seem to help; 2) I was running 1.0beta1 last week, and am now on 1.0beta3, but I'm still not seeing corrupt indexes/other dovecot files rebuilding themselves. I really can't stick with this solution if I'll always have to worry about manually fixing broken caches/indexes. 3) Any advice on fcntl/flock on OS X, particularly? They both appear to work, but I'd prefer to use the fastest/least resource intensive options for everything if possible. Thanks! -deano

[Dovecot] Corrupted transaction log file dovecot.index.log: unexpected end of file while reading header
by Matthias Saou 25 Mar '06

25 Mar '06

Hi, I'm using dovecot 1.0.0beta3 on a RHEL4 x86_64 server. I'm seeing this error each and every time a user checks his emails : Mar 15 18:19:34 s1 dovecot: pop3-login: Login: user=<user@domain>, method=PLAIN, rip=::ffff:195.x.x.x, lip=::ffff:195.x.x.x Mar 15 18:19:34s1 dovecot: pop3(user@domain): Corrupted transaction log file /home/vmail/domain/user/dovecot.index.log: unexpected end of file while reading header Mar 15 18:19:34 s1 dovecot: pop3(user@domain): Logout. top=0/0, retr=0/ del=0/2, size=1213 From my basic testing, this seemed harmless. But after putting this in production, it appears that when emails are retrieved, long ones always get truncated after a few kB, changing attachments into garbage :-( Has anyone seen this problem before? Any ideas what could be causing this?

[Dovecot] Segfault when parsing configuration on x86_64
by Matthias Saou 25 Mar '06

25 Mar '06

Hi, Using the exact same build of 1.0.beta3, one i386 and the other x86_64, I get segfaults upon startup with the x86_64 version when using the exact same dovecot.conf file. Here is the error : # dovecot -F Unexpected eof found when reading file 'UNOPENED' (Errcode: 0) Segmentation fault (core dumped) And the backtrace (I don't have symbols for all libs, sorry) : (gdb) bt #0 i_stream_next_line (stream=0x52c3a8) at istream.c:182 #1 0x000000000040e345 in i_stream_read_next_line (stream=0x52c3a8) at istream.c:201 #2 0x000000000040aaa9 in settings_read (path=0x41798e "/etc/dovecot.conf", section=0x0, callback=0x409580 <parse_setting>, sect_callback=0x409a50 <parse_section>, context=0x7fbffff880) at settings.c:222 #3 0x000000000040a0e1 in master_settings_read ( path=0x41798e "/etc/dovecot.conf", nochecks=false) at master-settings.c:1159 #4 0x000000000040875a in main (argc=2, argv=0x7fbffffa18) at main.c:762 #5 0x0000003d4341c4bb in __libc_start_main () from /lib64/tls/libc.so.6 #6 0x000000000040357a in _start () #7 0x0000007fbffffa08 in ??

() The really weird part is that I've managed to get my dovecot.conf in a state where the problem no longer happens, but simply adding a line with '#', or removing trailing spaces (normally harmless) on some config lines makes the error re-appear. My quick guess would be that something is wrong with the config file parser on 64bit archs... Actually, I've just made some more tests, and it is "partially" reproducible on i386. In this part of my configuration : auth default { mechanisms = plain passdb sql { args = /etc/dovecot-mysql.conf } userdb sql { args = /etc/dovecot-mysql.conf } } There is a trailing space on both "args = ..." lines. Well, if I remove them, I get this message with the i386 build. When I put them back, all is fine again.
