Hi!

That solution is bit overly broad way to solve this, I would instead recommend

service log { vsz_limit = 0 }

so that only service log is affected.

Do you get exactly same error message with that config or something else?

Ok... so for some reason the default_vsz_limit is too low for MacOS.

Can you try

default_vsz_limit = 2G?

We don't recommend setting it to 0.

I think this is happening because MacOS no longer supports RLIMIT_DATA. We'll try to look into this. default_vsz_limit = 0 seems good enough workaround.

This must be some change in MacOS 12 (Monterey). I have been running Dovecot for 10 years on MacOS with the same config, and only after upgrading to 12.0 did this issue surface.
