[Dovecot] run POP3S + IMAPS simultaneously?
by darren david 19 Nov '03

19 Nov '03

a quick one: is it possible to run POP3S and IMAPS services through dovecot at the same time? would i just uncomment both "login = imap" and "login = pop3" in /etc/dovecot.conf? or can i only run one at a time? apologies if the answer is obvious, i'm just still trying to wrap my head around all of this. thanks, darren david

[Dovecot] error msgs about missing ssl/tls support
by Kai Vehmanen 18 Nov '03

18 Nov '03

Hi, I've been just testing 0.99.10.2 and had a really hard time getting the new Dovecot to start properly. First I thought it was an error in my old dovecot.conf, but the actual problem turned out to be simply that Dovecot was compiled without SSL/TLS support (I hadn't noticed this), but dovecot.conf on the other hand specified SSL/TLS ports. The error messages might be a bit more informative in this case. Currently I only got this to my logs: --cut-- Nov 18 18:17:00 dovecot: Dovecot starting up Nov 18 18:17:01 imap-login: BUG: SSL initialization parameters not given while they should have been Nov 18 18:17:01 imap-login: BUG: SSL initialization parameters not given while they should have been Nov 18 18:17:01 pop3-login: BUG: SSL initialization parameters not given while they should have been Nov 18 18:17:01 imap-login: BUG: SSL initialization parameters not given while they should have been Nov 18 18:17:01 dovecot: Login process died too early - shutting down Nov 18 18:17:01 dovecot: child 18482 (login) returned error 89 Nov 18 18:17:01 dovecot: child 18481 (login) returned error 89 Nov 18 18:17:01 dovecot: child 18480 (login) returned error 89 Nov 18 18:17:01 dovecot: child 18479 (login) returned error 89 --cut-- ... and Dovecot would exit. Running Dovecot under gdb would just exit (even with -F), and segfault if ran under strace. So it took a while before I realized that configure had not even detected SSL/TLS... Oh well, not a big thing, but still something to keep in mind. -- http://www.eca.cx Audio software for Linux!

The problem is not with passwords that are stored in the db in digest-md5 format (i.e., as an md5 hash of user:realm:password), but with dovecot's password_generate() that takes the username and password and hashes it on the fly.

I'll see if I can get that done. Thanks Timo. Send me a patch when you're done and I'll test it. Matt

[Dovecot] Children, HasChildren
by Miquel van Smoorenburg 17 Nov '03

Hello, I'm using dovecot 0.99.10.2 on a debian box. Mailstore is maildir. If I list the IMAP hierarchy in mutt (debian, 1.5.4+20031024-1) it shows all my plain mailboxes as having subfolders - while none of them have. I straced mutt and this is the IMAP exchange (a bit reformatted for readability): write(6, "a0001 LSUB \"\" \"%\"\r\n", 19) = 19 read(3, " * LSUB () \".\" \"Drafts\" * LSUB () \".\" \"INBOX\" * LSUB () \".\" \"Sent\" * LSUB () \".\" \"Trash\" * LSUB (\\Noselect \\Children) \".\" \"broadband\" * LSUB (\\Noselect \\Children) \".\" \"cistron\" * LSUB (\\Noselect \\Children) \".\" \"debian\" * LSUB (\\Noselect \\Children) \".\" \"ip\" * LSUB (\\Noselect \\Children) \".\" \"lists\" * LSUB (\\Noselect \\Children) \".\" \"prive\" a0001 OK Lsub completed. ", 1024) = 374 Now this is strange - I read RFC3348 and shouldn't \\Children be \\HasChildren, also shouldn't the plain mailboxes (first four) be listed with \\HasNoChildren ? Mike.

[Dovecot] Corrupted index files
by Tomi Hakala 17 Nov '03

17 Nov '03

Hi, I'm playing with Dovecot in a lab environment and got it in state where it crashes on every incoming connection. I moved mail spool from ext2 file system to a ReiserFS on a another disk, mount point changed from /var/vmail to /spool/vmail. After that I managed to open mailbox and I moved about 2000 messages from INBOX to a subfolder. Then I tried to open mailbox with POP3 and it didn't succeed, from that point pop3d and imapd died every time I logged in until I removed all index files by hand. This is what I have in logs. imap-login: Nov 17 13:30:53 Info: Login: tomi.hakala(a)xx.fi [xx.xx.xx.xx] pop3-login: Nov 17 13:32:04 Info: Login: tomi.hakala(a)xx.fi [xx.xx.xx.xx] pop3(tomi.hakala(a)xx.fi): Nov 17 13:32:04 Error: Corrupted index file /spool/vmail/xx.fi/tomi.hakala(a)xx.fi/Maildir/.INBOX/.imap.index: Sequence 1848 not found from binary tree (5398 msgs says header) pop3-login: Nov 17 13:32:12 Info: Login: tomi.hakala(a)xx.fi [xx.xx.xx.xx] pop3(tomi.hakala(a)xx.fi): Nov 17 13:32:21 Error: Couldn't lock created modify log file /spool/vmail/xx.fi/tomi.hakala(a)xx.fi/Maildir/.INBOX/.imap.index.log imap(tomi.hakala(a)xx.fi): Nov 17 14:09:32 Error: IndexID mismatch for modify log file /spool/vmail/xx.fi/tomi.hakala(a)xx.fi/Maildir/.INBOX/.imap.index.log imap(tomi.hakala(a)xx.fi): Nov 17 14:09:33 Panic: file mail-tree-redblack.c: line 187 (rb_left_rotate): assertion failed: (node[x].right != RBNULL) dovecot: Nov 17 14:09:33 Error: child 19984 (imap) killed with signal 6 imap-login: Nov 17 14:27:24 Info: Login: tomi.hakala(a)xx.fi [xx.xx.xx.xx] imap(tomi.hakala(a)xx.fi): Nov 17 14:27:24 Panic: file mail-tree-redblack.c: line 232 (rb_right_rotate): assertion failed: (node[y].left != RBNULL) dovecot: Nov 17 14:27:24 Error: child 10478 (imap) killed with signal 6 -- Tomi Hakala

[Dovecot] Problem with DIGEST-MD5 authentication and plaintext passwords
by Matthew Reimer 17 Nov '03

17 Nov '03

I wasn't able to get DIGEST-MD5 authentication working with passwords stored as plaintext until I tweaked password_generate() to make it not use the domain portion of user(a)domain.com as the realm. Both evolution and kmail send the email address as the username with no realm; when dovecot tries to convert the username to user + realm, the hash is different and so DIGEST-MD5 authentication fails. Having password_generate() hash user@domain.com::password instead of user:domain.com:password fixes it. I need this to work because I need to support all of PLAIN, CRAM-MD5, and DIGEST-MD5 at the same time. Timo, do you think this is a proper fix, or are kmail and evolution broken? Matt

[Dovecot] MySQL patch + Debian
by James Tyson 17 Nov '03

17 Nov '03

Hi folks. Sorry to post here about a patch that hasn't been officially integrated into Dovecot, however I am trying to get it going and seem to have hit a dead end. I downloaded the Debianised source for Dovecot (0.99.10-9) from sarge: > wedge:/usr/local/src# apt-get -t testing source dovecot then applied the latest MySQL patch that I could find on the list: > wedge:/usr/local/src/dovecot-0.99.10# cat ../dovecot-mysql.patch | > patch -p 2 and manually fixed a merge issue with src/auth/master-connection.c, fiddled with the debian changelog to indicate the patch and then used dpkg-buildpackage -b to compile the package. Everything looked to build alright and I grepped the output to make sure that it compiled userdb-mysql.o and passdb-mysql.o into dovecot-auth. Problem is that dovecot-auth says "Unknown userdb type 'mysql'" and an ldd of /src/auth/dovecot-auth shows no libmysqlclient10: > wedge:/usr/local/src/dovecot-0.99.10# ldd src/auth/dovecot-auth > libpam.so.0 => /lib/libpam.so.0 (0x4001a000) > libldap.so.2 => /usr/lib/libldap.so.2 (0x40022000) > libpq.so.3 => /usr/lib/libpq.so.3 (0x4005a000) > libcrypt.so.1 => /lib/libcrypt.so.1 (0x4006e000) > libdl.so.2 => /lib/libdl.so.2 (0x4009c000) > libc.so.6 => /lib/libc.so.6 (0x4009f000) > liblber.so.2 => /usr/lib/liblber.so.2 (0x401cd000) > libresolv.so.2 => /lib/libresolv.so.2 (0x401da000) > libsasl2.so.2 => /usr/lib/libsasl2.so.2 (0x401ec000) > libgnutls.so.7 => /usr/lib/libgnutls.so.7 (0x401fe000) > libssl.so.0.9.7 => /usr/lib/i686/cmov/libssl.so.0.9.7 > (0x40231000) > libcrypto.so.0.9.7 => /usr/lib/i686/cmov/libcrypto.so.0.9.7 > (0x40260000) > libkrb5.so.17 => /usr/lib/libkrb5.so.17 (0x40351000) > libnsl.so.1 => /lib/libnsl.so.1 (0x40387000) > /lib/ld-linux.so.2 => /lib/ld-linux.so.2 (0x40000000) > libtasn1.so.0 => /usr/lib/libtasn1.so.0 (0x4039c000) > libgcrypt.so.1 => /usr/lib/libgcrypt.so.1 (0x403aa000) > libz.so.1 => /usr/lib/libz.so.1 (0x403e8000) > libcom_err.so.1 => /usr/lib/libcom_err.so.1 (0x403f7000) > libkrb.so.1 => /usr/lib/libkrb.so.1 (0x403f9000) > libasn1.so.6 => /usr/lib/libasn1.so.6 (0x40415000) > libroken.so.16 => /usr/lib/libroken.so.16 (0x40435000) > libdb3.so.3 => /usr/lib/libdb3.so.3 (0x40445000) Anyone know what I'm missing? --- James Tyson Director, Giant Robot Ltd http://www.giantrobot.co.nz/
