The alias works fine. It's just an auth request. I'll live with it. Sent from my Sprint Samsung Galaxy S8+. -------- Original message --------From: Bill Shirley <bill(a)KnoxvilleChristian.org> Date: 7/18/17 11:24 PM (GMT-06:00) To: dovecot(a)dovecot.org Subject: Re: passwd-file, getting invalid uid 0 Unless your userid is also zero, my guess is that Exim isn't using the alias. This message (to me) says "I can't deliver to 'root' because that userid is zero". On Postfix, you have to run 'newaliases' after changing /etc/aliases.

passwd-file, getting invalid uid 0

observium graphs
by Thomas Reifferscheid 18 Jul '17

18 Jul '17

Hello dovecot list, I'm in the middle of creating a plugin for observium[1] and would like to have it create[2] statistical graphs of my dovecot server [3]. The current state can be found here: https://image.ibb.co/efOO9a/dovecot.png However for visibility purposes it doesnt make sense and have observium plot two data sources with different orders of magnitudes right into one graph. So I'd like to ask for your valuable recommendations as for: - What kind of data should be graphed? Global stats or on a per domain level? - What data types to graph? (e.g. stats, getrusage, io, storage, auth check https://wiki2.dovecot.org/Statistics#line-65 for details) - What values should be combined into a single graph? - How often would you reset stats (cronjob calling doveadm stats reset)? Thanks Thomas [1]: http://www.observium.org/ [2]: http://docs.observium.org/apps/ [3]: http://docs.observium.org/developing/add_app/

Using user@domain as your ID solved your problem, and this side issue of which hash scheme you're using is probably irrelevant. You misunderstand what {SHA512-CRYPT} does compared with {SHA512}. It is normal to get a different hash with the same password when you regenerate the hash because a different random salt was chosen (the part between the '$6$' and the next '$') -- it used as part of the hash computation. {SHA512} is a straight saltless hash -- the same password maps to the same hash. This makes it prone to dictionary attacks (i.e. pre-generated tables of plaintext/hash values). If you support both schemes, SHA512-CRYPT is much stronger. Joseph Tam <jtam.home(a)gmail.com>

Dovecot Statistics
by Doug Hardie 16 Jul '17

16 Jul '17

I tried to setup statistics as shown on the Statistics wiki page. I encountered a problem with the mail_plugins for imap. in the protocol imap configuration the wiki shows adding imap_stats to mail_plugins. When I do that, dovecot stops authenticating and throwing error messages: Jul 15 12:47:46 mail dovecot: imap(doug)[10.0.1.251]<osGhcGBUmsgKAAH7>: Error: Couldn't load required plugin /usr/local/lib/dovecot/lib95_imap_stats_plugin.so: Plugin stats must be loaded also (you must set: mail_plugins=$mail_plugins stats) Jul 15 12:47:46 mail dovecot: imap(doug): Error: Internal error occurred. Refer to server log for more information. Changing that line to just add stats to mail_plugins resolves the problem. Hopefully that is an error in the wiki... However, in looking at the stats, I don't ever see any values for any of the auth_ values. They all show zero even though there have been numerous authentications by dovecot and postfix. I also notice that there is a new statistics output about every 3 minutes. It appears that the numbers are only for that 3 minute window. Is there a way to set the statistics so that I can see the last 24 hours, or the previous day? -- Doug

Hi, is it possible to run a post-login script on proxy side? When a user is 'proxied' away, the standard post-login script seems to be skipped. I want to update last login datetime but only proxy has access to user database (so i cannot run it on backends). azur

From the log files you've shown, you were able to authenticate "dsmith". Your mail reader tells you otherwise? Joseph Tam <jtam.home(a)gmail.com>
