Dear Mr. Sir,

It means that MAIL FROM address must be same user of SASL, if different, server rejects.

SASL user = userXXtest.com, MAIL FROM = userXXtest.com , Accept
SASL user = userYYtest.com, MAIL FROM = userYYtest.com , Accept

SASL user = userXXtest.com, MAIL FROM = userYYtest.com, Server rejects

How can I do to fix this problem ( I do not use MySql, LDAP ) ?

With best regards,

smtpd_sender_restrictions = reject_unlisted_sender
       reject_sender_login_mismatch
       permit_sasl_authenticated
       reject_unauthenticated_sender_login_mismatch
       reject

permit_sasl_authenticated permit user2test.com's email.
