Don't use reject_sender_login_mismatch for mail from a trusted relay
host.
smtpd_recipient_restrictions = reject_unauth_pipelining,
reject_non_fqdn_sender, reject_non_fqdn_recipient,
reject_unknown_sender_domain, reject_unknown_recipient_domain,
permit_mynetworks, reject_sender_login_mismatch,
permit_sasl_authenticated, reject_unauth_destination
Add the trusted relay hosts (or better, their network range) to
main.cf:mynetworks.
