Hi,
When installing dovecot with the default config, after generating the
certificates and changing login.conf for dovecot according to pkg-readme,
dovecot will show the following warning at startup:
"Warning: fd limit (ulimit -n) is lower than required under max.
load (512 < 1000), because of default_client_limit"
(The commented default_client_limit = 1000 in
/etc/dovecot/conf.d/10-master.conf)
This warning is visible in /var/log/maillog.
When starting the daemon with rcctl -d start dovecot it is visible on stderr.
Reproducable on:
* OpenBSD 6.4 (syspatched), amd64
dovecot-2.2.36
* Fresh installed OpenBSD 6.5 snapshot (of 2019-04-08), amd64
dovecot-2.3.5.1 (7ec6d0ade)
Below is a patch to increase the defaults for dovecot in login.conf for the
documentation /usr/local/share/doc/pkg-readmes/dovecot
diff --git mail/dovecot/pkg/README-server mail/dovecot/pkg/README-server

@@ -12,7 +12,7 @@ user and processes in their own login(1) class with tuned
resources.
For example, add this to the login.conf(5) file:
dovecot:\
-:openfiles-cur=512:\
+:openfiles-cur=1024:\
:openfiles-max=2048:\
:tc=daemon:

Kind regards,
