[Dovecot] Receive Mail via lmtp/tcp
by Denny Schierz 20 May '10

20 May '10

hi, we have IMAP and SMTP (sendmail(solaris)) on different hosts. Sendmail delivers Mails via LMTP to Cyrus and Cyrus puts the mails into the (hopefully) right box. Now I want to replace the Cyrus host with Dovecot. I've searched a bit in Google but there isn't much about LMTP via TCP in combination with DoveCot. Version 2 seems to be get the feature, but we have round about 5k users, so beta is no choice. Also I red something about maidag (mailutils from Gnu) that could do the Job, but maybe there is a better way. I do not want to install Postfix (or any other SMTP service) on that IMAP Server. So I'm asking is there anybody who has the same construct. Important is, that Quota full etc. messages (RFC) gets back to sendmail, so that the MTA reject the mails, before accepting. cu denny

I don't remember what the last conclusions were :) Anyway I'd probably accept patch to Dovecot, but maybe not yet advertise supporting SPECIAL-USE in capability. > > But the main thing I'm not sure about is where should the flag information be stored? Should it even be per-user option? If yes, should it maybe be combined with autocreate plugin? > Yeah advertise SPECIAL-USE before IANA registred keyword isn't good thing. I don't think this really need per-user option. This is basically "system folders" and MUA will decide on their local names. Combining with autocreate plugin seems reasonable.

[Dovecot] logging
by James Devine 20 May '10

20 May '10

I am looking through the logging options and wondering if there are a couple of things that we can do 1. Logouts don't seem to show the IP address of the logout, we typically see multiple sessions at a time and wondering if there is a way to tie the logouts to an IP 2. POP logouts show the number of messages retrieved/deleted but I don't see a way to do this with IMAP, is there a logout option for this with imap? Thanks

I'm still kinda weak on Python (don't know all the cool tricks, yet), and Pike isn't found universally, so things would need to be in C for me to do it and it to be widely usable. And that's for later when I get some free time.

[Dovecot] looking for IMAP testing tool
by Phil Howard 19 May '10

19 May '10

I'm looking for an IMAP testing tool, suitable to use with Dovecot IMAP. It needs to support TLS, STARTTLS, and login/authentication. It needs to be able run from command line, shell scripts, and even do so under cron jobs (e.g. a way to supply the password to use w/o a terminal prompt). Typical interactive mail clients just don't cut it (even the text mode ones). One reason is I need to do the tests on a number of machines, under a number of user and domain names, and with a variety of parameters or destinations. This is for a suite of regression tests I am putting together intended to verify that configuration changes do not break things (or unbreak things that are supposed to not work). Anyone ever heard of such a tool? Open source would be preferred (better yet, my favorite programming languages: C, Pike, Python).

[Dovecot] problem compiling pigeonhole + my fix
by Andreas Schulze 19 May '10

19 May '10

hello, yesterday I tried to package dovecot-2.0beta5 + pigeonhole from Mercurial repository. I put pigeonhole as a subdir in the dovecot sourcetree. Following http://hg.rename-it.nl/dovecot-2.0-pigeonhole/raw-file/tip/INSTALL I called ./autogen.sh; ./configure --with-dovecot=..; make In the buildprocess I saw this output ( from autogen.sh ): Putting files in AC_CONFIG_AUX_DIR, `..'. libtoolize: `config.guess' exists: use `--force' to overwrite libtoolize: `config.sub' exists: use `--force' to overwrite libtoolize: `ltmain.sh' exists: use `--force' to overwrite I dont know *why* AC_CONFIG_AUX_DIR is .. but in .. there are the mentioned files (from dovecot) already present. The following make failed with less helpfull errors. -> my fix is to call "autoreconf -i -f" again after autogen.sh should -f be added to autogen.sh ? -- Andreas Schulze Internetdienste | P532 DATEV eG 90329 Nürnberg | Telefon +49 911 319-0 | Telefax +49 911 319-3196 E-Mail info @datev.de | Internet www.datev.de Sitz: 90429 Nürnberg, Paumgartnerstr. 6-14 | Registergericht Nürnberg, GenReg Nr.70 Vorstand Prof. Dieter Kempf (Vorsitzender) Dipl.-Kfm.

Re: [Dovecot] A new director service in v2.0 for NFS installations

We've talked about that before, that the proxy could for instance fall back to itself as the 'final server'. The people in here want to use their existing monitoring script that would do "ssh host doveadm director remove 1.2.3.4". But on top of that, yeah, maybe proxy itself could tell director that some host is down and retry the lookup. Although determining when it's down might not be fully reliable always, so I'm a bit worried that proxy could sometimes fail to connect to a mail server even if it's up (but e.g. with high load, temporary small network problem, etc).
