Is there more detail needed to finally solve this? The temporary fails caused by LMTP not reaching the 'RCPT TO' stage get pretty annoying in the light of backscatter hitting the server:
Nov 19 08:16:09 spectre postfix/smtpd[21386]: NOQUEUE: reject: RCPT from emea01-am1-ndr.ptr.protection.outlook.com[157.56.116.99]: 450 4.1.1 DC21DEC5-D7F9-41FE-B16C-1ECC8536C40F@leuxner.net: Recipient address rejected: unverified address: lost connection with spectre.leuxner.net[private/dovecot-lmtp] while sending MAIL FROM; from=cocacola0004@mentesbrim.onmicrosoft.com to=DC21DEC5-D7F9-41FE-B16C-1ECC8536C40F@leuxner.net proto=ESMTP helo=
To reproduce simply add 'reject_unverified_recipient' to 'smtpd_recipient_restrictions'...
is dovecot knowing all alias addresses ?, with dovecot-lda its done in postfix before delivering to dovecot-lda, so if the recipient here is a valid mailbox it should work, but i think dovecot needs alias support to be used same way as postfix does
when it works it would be a dream, seems we are not there yet
