Just a follow-up to correct a couple of things in case anyone is reading this in future:
main.cf includes: # Route inbound for valid recipients to dovecot virtual_transport = lmtp:unix:/var/spool/postfix/private/dovecot-lmtp lmtp_use_tls = no virtual_mailbox_domains = pjb.cc virtual_mailbox_maps = hash:/usr/local/etc/postfix/vmailbox virtual_alias_maps = hash:/usr/local/etc/postfix/virtual vmailbox: ml-postfix-us...@pjb.cc off-to-lmtp virtual contains: mb170...@pjb.cc ml-postfix-us...@pjb.cc # +LOTS of others The Dovecot users file includes: ml-postfix-us...@pjb.cc:,<passwordstuff>:10043:10000::/var/vhome/%n # +LOTS of others All working as expected. -- Cheers, Phil
