This sounds like macOS not liking RLIMIT_DATA. You can try setting default_vsz_limit = 0 and see if that helps.

I fixed the issue with Dovecot not starting on macOS Ventura by adding this to 10-master.conf:

service log { vsz_limit = 0 }

But now when I try to login via Imap on port 143 I get the same error for imap-login:

Quitting Dovecot and restarting and I now get:

Then trying to connect on port 143 log says:

Any suggestions? This is really driving me crazy!
