Perhaps the above was not clear. Post, in the body of the email message (don't upload attachments) relevant NON-VERBOSE logs showing errors from: postix/smtp (not postfix/smtpd) postfix/master Outbound mail is sent by postfix/smtp, your smtp(8) delivery agent is terminating abnormally. This is logged, post *those* logs. -- Viktor.
