I see no specific entry for dovecot in /etc/login.conf on my systems. Did you
add that yourself perhaps?
If so then I think the daemon entry in /etc/login.conf would normally (on
pre-OpenBSD 7.1 systems) apply which is:
daemon:\
:ignorenologin:\
:datasize=4096M:\
:maxproc=infinity:\
:openfiles-max=1024:\
:openfiles-cur=128:\
:stacksize-cur=8M:\
:tc=default:
So the settings in /etc/login.conf.d/dovecot are actually an increase, not a
decrease compared to the default.
If you find that these values are not high enough then by all means edit
/etc/login.conf.d/dovecot to your liking.
Note that OpenBSD 7.1 introduced the /etc/login.conf.d/${class} mechanism which
overrides the corresponding classes in /etc/login.conf, see login.conf(5). Thus
if you updated from a modified older system and missed this change then the
situation you described could occur.
