The most likely reason for this error is that Postfix does not allow the XFORWARD for command from the back-end to postfix. Check whether postfix main config contains the following line: smtpd_authorized_xforward_hosts = 127.0.0.1/32 See https://www.postfix.org/postconf.5.html for more information on smt pd_authorized_xforward_hosts Kind regards, Martijn Brinkers -- CipherMail email encryption Email encryption with support for S/MIME, OpenPGP, PDF Messenger and Webmail Messenger Email encryption with support for S/MIME, OpenPGP, PDF Messenger and Webmail Messenger
