Some more information would be useful, but try setting mail_debug=yes and then check your log files for more
Yeah, would have provided more if I had more info. What I needed was to set min processes for lmtp service lmtp { process_min_avail = 1 } Otherwise there was no lmtp process available and 2nd in postfix' main.conf I had to add local_transport = lmtp:unix:private/dovecot-lmtp I *guess* that this is due to the latest update of macOS that may have brought new postfix binaries (at least the time stamps suggest this), where some settings/defaults have changed.
