In particular, send output of 'postconf -n'. Also, when you post logs,
post full log lines.

by default, postfix rejects mail to invalid recipients, except for relay
domains, where you need to specify the relay_recipient_maps. so show
your postcon -n.
also, do not use wildcards in virtual_alias_maps or canonical. This
breaks recipient validation.
