Hello Aki, Timo, Thanks a lot for your answers. I'll test with setting mail_max_userip_connections from DB first and tell if it works. If it does not, I'll go with the policy server. Again, thanks a lot. On 03.07.2017 9:29, Timo Sirainen wrote: > On 3 Jul 2017, at 9.24, Aki Tuomi <aki.tuomi at dovecot.fi> wrote: >> >> >> On 02.07.2017 10:53, Alexey Asemov

Easiest would be

I can confirm setting mail_max_userip_connections from database in userdb query *does not* work at all. User can still open multiple connection above the limit, seems like it has no effect. I thoroughly checked DB response and it contains proper field name/value. I am using dovecot 2.2.31. Also, I have mail_max_userip_connections set globally in the dovecot configuration file and wonder if

Hi, I'm curious about some of the larger dovecot installs out there and what your current active user load looks like per server. Realistically, how many active IMAP sessions are some of you maintaining? At what point did you find the load became unmanageable? I know there's a lot of different factors involved in this, but I'm just looking to get a rough idea of what I can expect

I know it seems at least unusual. But I would like to know if someone knows a software that can proxy multiple pop3 and imap connections to the same account and use only imap connections to the real server. I need it because I've to deal with two pieces of software that are out of my control: - 1 - A certified mail provider that states something that I would like to know if it's really

Hello List, I'm building a dovecot-2.2.27 RPM for CentOS 7 and running into some issues The dovecot.spec (http://pkgs.fedoraproject.org/cgit/rpms/dovecot.git/tree/dovecot.spec) file runs 'autoreconf -I . -fiv' for aarch64 support just before the %configure option but is failing This worked fine on <= 2.2.26.0 when there was an m4/*.m4 directory (with *.m4 in it) in the

Hi, During discussions with the boss we've speculated about having users having only specific services available. One of the ideas was to have users being able to specify if they wanted POP3 or IMAP and whether we could limit their access to one or the other server side. We use MySQL for the userdb and passdb lookups at the moment. Is it possible to specify separate auth files with different

When I set this in master.conf: service imap { service_count = 5 } I see this error when two imap users log in: Nov 11 16:54:16 server dovecot[5432]: imap-login: Login: user=<user1>, method=PLAIN, rip=10.100.0.84, lip=10.80.0.163, pid=5573 Nov 11 16:54:31 server dovecot[5432]: imap-login: Login: user=<user2>, method=PLAIN, rip=::1, lip=::1, secured, pid=5573 Nov 11

Hi, I'd like to have a log per user, and protocol (imap+pop3), where this log would tell me/save the message sender+subject+operation (deleted, marked to expunge/other/was read/other). Is there something similar to this that already exists? If not is there something like this on the TODO/whishlist? Thanks in advanced, Jorge Bastos

Hi Is it safe to use IMAP and POP3 simultaneously to access the same inbox (using Maildir structure)? Thanks! Stanis?aw -------------- next part -------------- A non-text attachment was scrubbed...

Quoting Ruga <ruga at protonmail.com>: > Comparison of Dovecot, Uwash, Courier, Cyrus and M-Box: > http://www.isode.com/whitepapers/mbox-benchmark.html Wow. That comparison is only 11.5 years old. The "default" file system of reiserfs and gcc-3.3 were dead giveaways. I suspect Dovecot's changed a tad since that test. =R=

Hi! I'm new to this list and i could not find a way to search through the already posted articles, so please forgive me if this subject has been discussed before. Our security scanner stumbled over the IMAPs server i've set up recently using dovecot on a RedHat Enterprise 64bit Server. The security scanner found an error regarding a new SSL security leak named "BEAST". The

I''ve been trying to track down the culprit of erratic behaviour and crashes on my production server (which is split into a number of Xen instances), so set up a staging server so that I could really try to get to the bottom of it. The staging server (also split with Xen) is set up pretty much identically as far as the mongrel_cluster server is concerned (the production box has two
