Some more information: the issue has just occurred, again on an instance without the "service_count = 0" configuration directive on pop3-login. I've observed that while the issue is occurring, the director process goes 100% CPU. I've straced the process. It is seemingly looping: ... ... epoll_ctl(13, EPOLL_CTL_ADD, 78, {EPOLLIN|EPOLLPRI|EPOLLERR|EPOLLHUP, {u32=149035320,

Hello dovecot! I administer a dovecot installation with 30k users. I've got 4 dovecot directors as frontend and 10 backends. The mailbox are now in maildir format, with maildir++ quota, on a shared netapp filer. Indexes are local on each backend. I'm reconfiguring the quota plugin: as a first step, I want to use the clone plugin to keep a copy of the quota on a redis database. Next,

Aha. Looks pretty cool, and it's really nice that it supports HTTP. On the other hand if I'm rate limiting the number of messages sent = number of times a client said RCPT TO, I guess it still has to be a postfix policy server? Anyway, thanks for pointing this out, I'm sure I'll use it :-) On 10/21/2017 02:16 PM, Aki Tuomi wrote: > Dovecot auth supports auth_policy_server

Hi, I struggle with directory hashing. I want something like this: /srv/mail/c/cf37a8dff5e360927ba10ab2 The final folder is simpel, as it is: %{sha256;truncate=96:user} But how do I get a first level from sha256? Unfortunately, the truncate option aligns only full 8bit and does not divide into low and high nibbles. How can I express this for sha256? in MD5 this would be %1Mu Many thanks in

Hi all; I've upgraded a ring of dovecot directors from 2.2.15 to 2.2.36. After the upgrade I've got some instability: a few time per day per server, seemly at random, the auth process stop responding and the clients cannot authenticate any more: Sep 6 14:45:51 imap-front13 dovecot: pop3-login: Warning: Auth process not responding, delayed sending initial response (greeting):

Hi list! I've recently updated a small dovecot cluster from 2.2.29 to 2.3.10. I've found an issue with variable expansion. My user/password database is on a mysql table, with password saved in plain text field. The cluster receives mail via lmpt and users fetch them via imap. On the 2.2.29 version, no issues. After the upgrade, I've found some lines in the log: Apr 14 14:36:05

Hi all; I've just compiled version 2.2.36.1 on a new debian buster (debian 10) and it seems that this patch https://github.com/dovecot/core/commit/ 63a74b9e8e0604486a15a879e7f1a27257322400.patch is needed to make it work. Without the patch, the authentication segfaults. *Simone Lazzaris* *Qcom S.p.A.* simone.lazzaris at qcom.it[1] | www.qcom.it[2] * LinkedIn[3]* | *Facebook*[4] [5]
