You need to configure stats service client limit and imap service client limit. Those are different services than imap-login service.

Morikawa-san, Your conf is wrong. Should be: quota_warning = storage = 95 %% quota-warning 95 %u Your conf: quota_warning = storage = 95 %% quota-warning 95% u There's a space between % and u. First of all, try the above and let us know if it changes. Kouga -----Original Message----- From: ????? <morikawa-k6 at itec.hankyu-hanshin.co.jp> Sent: Wednesday, October 28, 2020

Hi,Kouga-san When quota-warning works normally I'm sending an email to "From: <Postmaster at example.co.jp> to = <abc-xyz-unyo at example.co.jp>" When it doesn't work An email was sent to "From: <Postmaster at example.co.jp> to = <abc-xyz-unyo-sekkei>" "Recipient address rejected: User unknown in local recipient table" It will be.

kouga-san After copying and pasting, something went wrong. Actually "quota_warning = storage=95%% quota-warning 95 %u" It is set in. (In fact, I usually receive a notification email.)

We have upgraded dovecot from 2.0.9 (centos6) to 2.2.36 (centos8). If more than 1000 users log in, the following error will occur. ------------------------- Nov 16 11:33:00 xxxxxxxx dovecot[1361]: imap-login: Error: master(imap): net_connect_unix(imap) failed: Resource temporarily unavailable - http://wiki2.dovecot.org/SocketUnavailable (client-pid=1362, client-id=129834, rip=10.10.10.10, created

Morikawa, What do you mean by "logged-in user"? %u stands for the username. If, for an example, user "morikawa" exists in your dovecot server (I mean as local user), your quota warning configuration should be fine. But if user "morikawa" does not exist in your server, and, dovecot can't resolve the username to the mail address, then the quota warning mail be

Hi, all. we use quota-warning emails to notify you of quotas. In rare cases, the email address has changed to the logged-in user. (Because the address of %u is passed as the logged-in user.) So I couldn?t send the email with ?Recipient address rejected: User unknown in local recipient table?. Why does my email address change to a logged-in user? %u of "quota_warning = storage = 95 %%

Hello list, i run here an large mailsetup with some million mailboxes and got strange performance problems, cause i think i have overseen or forgotten an simple setting.

Can you enable 'verbose_proctitle=yes' and maybe compare with ss -tp output?

Hi Philips, I have the same error after upgrade from dovecot 2.2 to dovecot 2.3, could be related to "service stats", try to grep in the dovecot.log for "reached" and look for an error like: dovecot: master: Warning: service(stats): client_limit (1000) reached, client connections are being dropped If you find it add to 10-master.conf: service stats { ? client_limit =

Hi all, we have a problem about anvil, it seems that when we have a high load the dovecot stops to work. Sometimes it is sufficient to make a dovecot reload, but sometimes we have to restart it.

Hello everyone, we have a huge problem with dovecot and IMAP connections. we got the following errors: 39665 today dovecot: imap-login: Error: master(imap): net_connect_unix(imap) failed: Resource temporarily unavailable - http://wiki2.dovecot.org/SocketUnavailable (client-pid=29066, client-id=1755, rip=IP, created 562 msecs ago, received 0/4 bytes) we thinks this may be a problem with

While I not certain that this is related to the problem we are experiencing, we are also (more rarely) seeing these: dovecot: master: Warning: service(imap-login): process_limit (16) reached, client connections are being dropped imap-login was set to process_limit=16, client_limit=1250 (for a total of 20000 concurrent clients) on 2.2.27.

The load on our machines has gotten too high, so I started to see log messages that directed me to look at this page for config changes: https://pad.riseup.net/redirect#http%3A//wiki2.dovecot.org/SocketUnavailable One of the things I wanted to do on that page was to set the: service imap { service_count = 100 } but when I added that to the service imap block, and restarted dovecot, I see this

Especially some imap/pop3 login bursts could have caused errors like: imap-login: Error: net_connect_unix(imap) failed: Resource temporarily unavailable Fix in http://hg.dovecot.org/dovecot-2.2/rev/69179ca6007d Explanation & workaround in http://wiki2.dovecot.org/SocketUnavailable : Dovecot v2.2.0 - v2.2.6 were attempting to optimize host.domain lookups by doing them only once in the

Hi List, after upgrading dovecot from version 2.2.33.2 to 2.3.7.2 I got a lot of error messages like the following if the process count of imap processes reaches nearly 1000 (~950 (there are a few pop-connections)).
