[Dovecot] Small problem with src/lib/mountpoint.c
by Mike Brudenell 17 Jul '07

17 Jul '07

Greetings - Whilst playing with getting quotas from NFS-mounted filestores I've just discovered a slight problem with src/lib/mountpoint.c I had things working on a Solaris 10 test machine which had the mailstore mounted 'normally' using an entry in /etc/vfstab. However when I changed to use the automounter for the mailstore obtaining the quota broke. The problem lies with mountpoint_get(). On a 'normally' mounted filestore this obtains the device_path of the remote filestore in the form remoteservername.some.domain:/remote/path However when the mailstore was automounted I was instead getting back auto_direct which is the name of the automounter map we're using. The /etc/mnttab file has TWO entries for the auto-mounted filestore, like this: auto_direct /mailstore/messages/p autofs direct,ignore,dev=4740014 1184648400 crypt2.york.ac.uk:/vol/vol9/p /mailstore/messages/p nfs proto=tcp,xattr,dev=4700386 1184668792 Although there are two entries they have different device numbers. The mountpoint_get() function attempts to guard against this by checking the device number obtained matches that of the path being located. However for some reason I don't understand when getmntent() returns the FIRST of the above two entries it supplies the device number of the SECOND. Thus the device numbers match in the mountpoint_get() test and it thinks it has found the correct entry. This leads to the device_path being set to the map name -- auto_direct -- instead of the host:/path My fix is to add an additional fstype for the test to ignore: "autofs". The loop skips over any such mounts (along with the existing tests for "swap" and "ignore"). I'm attaching my minimal patch in case it's of help to anyone else. (Timo: would it be possible to get this added into the distribution code if you agree it's right?)

[Dovecot] Problem with Dovecot SASL in Postfix
by Chris McMacken 16 Jul '07

16 Jul '07

Ok lets try this again... I'm trying to configure my postfix server to use Dovecot as an SASL server and running into some problems. My server supports a couple of domain, I have multiple user/password files for multiple domains to make the files a little easier to manage. Not sure if this question should belong in the dovecot mailing list or the postfix one, but here goes anyway. I have everything configured to use CRAM-MD5 authentication, including my mail client. Here is the Dovecot -n output: mail# dovecot -n # /usr/local/etc/dovecot.conf log_path: /var/log/dovecot info_log_path: /var/log/dovecot.info protocols: imap pop3 ssl_disable: yes disable_plaintext_auth: no login_dir: /var/run/dovecot/login login_executable(default): /usr/local/libexec/dovecot/imap-login login_executable(imap): /usr/local/libexec/dovecot/imap-login login_executable(pop3): /usr/local/libexec/dovecot/pop3-login verbose_proctitle: yes first_valid_gid: 0 mail_extra_groups: mail mail_location: maildir:/home/vmail/%d/%n mail_executable(default): /usr/local/libexec/dovecot/imap mail_executable(imap): /usr/local/libexec/dovecot/imap mail_executable(pop3): /usr/local/libexec/dovecot/pop3 mail_plugin_dir(default): /usr/local/lib/dovecot/imap mail_plugin_dir(imap): /usr/local/lib/dovecot/imap mail_plugin_dir(pop3): /usr/local/lib/dovecot/pop3 imap_client_workarounds(default): delay-newmail outlook-idle netscape-eoh tb-extra-mailbox-sep imap_client_workarounds(imap): delay-newmail outlook-idle netscape-eoh tb-extra-mailbox-sep imap_client_workarounds(pop3): outlook-idle pop3_uidl_format(default): pop3_uidl_format(imap): pop3_uidl_format(pop3): %08Xu%08Xv pop3_client_workarounds(default): pop3_client_workarounds(imap): pop3_client_workarounds(pop3): outlook-no-nuls oe-ns-eoh auth default: mechanisms: plain cram-md5 passdb: driver: passwd-file args: /usr/local/etc/dovecot/%d/passwd userdb: driver: passwd-file args: /usr/local/etc/dovecot/%d/passwd socket: type: listen client: path: /var/spool/postfix/private/auth mode: 432 user: postfix group: postfix master: heres a sample line from one of the passwd files: chrism:{CRAM-MD5}a67a65704086a046b3f875d1eaac8cb5c6fd13406507fead30d9bcb1bf… and to login through SASL I am trying to use the username chrism(a)example.com when I use the full email address like this to login like this I get this output into my postfix log: Jul 10 18:46:59 mail postfix/smtpd[57343]: connect from unknown[12.244.148.123] Jul 10 18:46:59 mail postfix/smtpd[57343]: NOQUEUE: reject: RCPT from unknown[12.244.148.123]: 554 5.7.1 <chrism(a)gmail.com>: Relay access denied; from=<chrism(a)example.com> to=<chrism(a)gmail.com> proto=ESMTP helo=<[192.168.1.14]> Jul 10 18:47:00 mail postfix/smtpd[57343]: disconnect from unknown[12.244.148.123] (not actually using example.com but I changed it here) heres my smtpd_recipient_restricitons from postconf smtpd_recipient_restrictions = permit_mynetworks, reject_unauth_destination, permit_sasl_authenticated so when I use the full user name (chrism(a)example.com) it doesn't appear to even attempt logging into the sasl server.

[Dovecot] Getting quotas from an NFS-mounted filestore
by Mike Brudenell 16 Jul '07

16 Jul '07

Greetings - I was just wondering what the state of play was with regard to reading filestore-based quotas when the mailstore is NFS-mounted? Timo mentioned a little while ago that he'd be including it: http://www.dovecot.org/list/dovecot/2007-May/022594.html However it isn't in 1.0.1 and isn't mentioned in the release notes for 1.0.2. Is it going to be a 1.1 feature or will it appear before then? I'm asking because although I can't get the rquota-rquotad patch to build on Solaris I have found some code on the net which does do RPC based quota lookups. I'm toying with the idea of trying to modify rquota-rquotad to use this other code. However this is out of my area of knowledge so it will be an uphill battle ... so if reading quotas from NFS-mounted filestores will be coming Real Soon Now I'll probably just wait instead. So any ideas as to timescales, please?

[Dovecot] quota warning - take 2
by Nicolas Boullis 16 Jul '07

16 Jul '07

Hi, About one month ago, I sent a patch to this list to implement warnings when a user is close to reach his quota. I tried to follow Timo's advice to improve my code, and here (at last) is a new patch. Things I did not fix: - This patch is still for dovecot 1.0, as I will need warnings with dovecot 1.0. I may rewrite it for CVS HEAD in the future but can't promise. - I'm still using system() rather than fork()+exec()+waitpid() since I don't know a good time to run waitpid(). Comments are welcome. Timo, will you consider to add this to your unofficial patches? Cheers, Nicolas Boullis

[Dovecot] v1.0.2 released
by Timo Sirainen 15 Jul '07

15 Jul '07

http://dovecot.org/releases/dovecot-1.0.2.tar.gz http://dovecot.org/releases/dovecot-1.0.2.tar.gz.sig Fixes several bugs. This release also adds compatibility with upcoming Dovecot v1.1 so it'll be possible to upgrade to v1.1 and back to v1.0.2 without anything breaking. * dbox isn't built anymore by default. It will be redesigned so it shouldn't be used. + Maildir: Support reading dovecot-uidlist (v3) files created by Dovecot v1.1. - Maildir: "UIDVALIDITY changed" errors could happen with newly created mailboxes - If "INBOX." namespace was used, LIST returned it with \HasNoChildren which caused some clients not to show any other mailboxes. - Maildir++ quota: If multiple processes were updating maildirsize at the same time, we failed with "Unknown error". - IMAP: IDLE didn't actually disconnect client after 30 minutes of inactivity. - LDAP passdb/userdb was leaking memory - deliver: %variables in plugin {} weren't expanded - deliver: Don't bounce the mail if Sieve plugin returns failure

[Dovecot] How to stop POP clients from downloading mail after directory corruption
by Frank Church 15 Jul '07

15 Jul '07

Transferring my email from a Courier server, as well as some corruption in my dovecot installation caused all POP mails to be downloaded again. I surmised that the dovecot-uidlist file was not present in the first instance, and was probably out of sync in the second. Is there a way to do some reindexing and uid-list regeneration that can stop the problem from occurring? - Frank
