[Dovecot] Checking for strtoumax and strtoimax
by J Springer 08 Jan '09

08 Jan '09

Tru64 5.1b PK6 : dovecot 1.1.7 : cc Configuration checks for strtoumax and strtoimax are positive but both are unresolved during compilation. strtoq and strtouq checks are negative. I can modify compat.c to use "unsigned long ret = 0;" in place of strtoumax (does this break anything?) and/but I would like to know how to handle strtoimax. Thanks in advance.

[Dovecot] allow_nets overridden by cache
by Guy 08 Jan '09

08 Jan '09

Hi, I've just started trying allow_nets on one of my servers. I have auth_debug and auth_verbose both enabled and the output is as follows: Oct 28 13:05:48 mink dovecot: auth-worker(default): auth(user(a)domain.net,x.x.x.x): allow_nets: Matching for network 127.0.0.1/8 Oct 28 13:05:48 mink dovecot: auth-worker(default): auth(user(a)domain.net,x.x.x.x): allow_nets: Matching for network 10.0.7.176/28 Oct 28 13:05:48 mink dovecot: auth-worker(default): passdb(user(a)domain.net,x.x.x.x): allow_nets check failed: IP not in allowed networks Oct 28 13:05:50 mink dovecot: auth(default): client out: FAIL 1265 user=username(a)aluminati.net Oct 28 13:05:50 mink dovecot: auth(default): cache(user(a)domain.net,x.x.x.x): hit: <hidden> user=user(a)domain.net Oct 28 13:05:50 mink dovecot: auth(default): client out: OK 1266 user=user(a)domain.net auth_cache_ttl is set to 300. If I set it to 1 then the allow_nets successfully rejects. Once I set it back up to 300 the cache overrides the result from the allow_nets check and let's the account log in even though the allow_nets check fails. I've tried waiting for longer than the 300 seconds and then logged in again, but I still get the same result as above. Is there a gotcha that I'm unaware of or have I done something stupid (which seems the most likely :P)? Thanks Guy -- Don't just do something...sit there!

[Dovecot] Setting IMAP keywords/flags on delivery
by Matt Doran 08 Jan '09

08 Jan '09

Hi there, We've been long time users of Dovecot, and have found it a great IMAP server. I don't think we've had any serious problems in the 3-4 years of use. So great work. :) We have a IMAP inbox that is accessed by a number of different users from Thunderbird. We have a rule in Thunderbird to flag new emails as "TO DO", so someone can unflag the email once it has been actioned. This process works fairly well for a simple workflow, but problems arise when someone connects to the inbox with a Thunderbird instance that doesn't have the "TO DO" rule configured. The email will not be flagged properly. :( I'd like to be able to set this flag/keyword when the mail is delivered to the inbox, on the server side. That way the flag will be set no matter which client accesses the Inbox first. We currently use mail drop for our server-side mail filtering .... and would like to do a similar thing with this flagging process. We're using Dovecot 1.0.15 on Debian Testing, and use Maildir storage and maildrop as our delivery agent. I've read about how the keywords and Thunderbird labels work in the wiki article here (http://wiki.dovecot.org/MailboxFormat/Maildir) So I could probably write some sort of script to query the "dovecot-keywords" file, and rename the Maildir file to set the appropriate flag. But this sounds a like a bit of a hack, and maybe a little dangerous. Does anyone have any recommendations as to how I could achieve something like this? I'm keen to hear any ideas, whether it's through scripting, or some sort of scriptable/command-line IMAP client. Ideally, we'd have a way to set the flag at the time when the mail is delivered.... or when the first client retrieves any new mail?

[Dovecot] Default dirs in ./configure?
by Peter Lindgren 08 Jan '09

08 Jan '09

Hi! I try to build a new 1.1.7 installation. Since I'm not a large sysadmin, just my own private mail server admin, I just wonder why the sysconf and state dirs defaults to $prefix? Maybe I'm old-school, but isn't /etc and /var, respectively, a better default than /usr/local? Should require two new variables in the configure script, though. (and yes, I know I set them with --sysconfdir=/etc --localstatedir=/var --sharedstatestatedir=/var ) /Peter -- Peter Lindgren http://www.norrskenkonsult.com

Re: [Dovecot] login fails when username has apostrophe
by Karl Latiss 08 Jan '09

08 Jan '09

Sorry to bump so quickly but I have a handful of users who can't log in at the moment and would like to get this fixed. Am I missing a config option or is this a bug? The only reference I can find in the mailing list archives is that this configuration should be supported.

[Dovecot] Problem with opening ports in alpha5 ?
by Bruce A. Mallett 07 Jan '09

07 Jan '09

If I leave the "listen" value as the default in /etc/dovecot.conf I'll get a message similar to the following on each port that it tries to open during startup: # dovecot -F Fatal: listen(::, 143) failed: Address already in use If I set either: listen = * or listen = [::] then it will start up fine. Perhaps it is as though the code tries to open the port twice for both ip4 and ip6? - Bruce

[Dovecot] Apple patches 11-14
by Mike Abbott 07 Jan '09

07 Jan '09

These are the last patches for now, and they're small. The base for each of them is dovecot-1.1.7 + Apple patches 9 and 10, again not because of a logical dependency but just because these patches change parts of the earlier patches. Patch #11 adds a few dtrace providers to key points in the code. We are still validating the correct placement and usefulness of these. One cool thing about dtrace is that when not in use the hooks literally are just a couple of no-op instructions. Patch #12 increases many listen queue sizes to handle high loads better. The new values are not necessarily the best possible values but they do allow more throughput. Patch #13 makes dovecot adapt to dynamic host identity changes upon config reload. Patch #14 covers three miscellaneous changes, to support more file descriptors and an "unlimited" number of mail processes, and a different default mail user. That's all our patches for now!

[Dovecot] Obtaining the chroot-cage directory of the mailstore
by Stefan Jurisch 07 Jan '09

07 Jan '09

Hello, I'd like to find a function in the sourcecode which enables me to get the chroot-path of the mailstore, so I can concatenate it with the result of mail_storage_get_mailbox_path to get the full path of a mailbox within the filesystem. Does such a function exist? Who can help me? Thanks in advance.

Hello, Happy new year. I have a dovecot with exim installation. I am using virtual users for mail and IMAP.
