- Plesk for Linux
The following record can be found in
# postfix/local: 2E572342FF3: to=<firstname.lastname@example.org>, orig_to=< email@example.com>, relay=local, delay=0.15, delays=0.14/0/0/0, dsn=5.2.1, status=bounced (This address no longer accepts mail. )
Why does it appear?
It appears because mail bounce is set in Plesk > Domains > example.com > Mail Settings.
When an email is sent to an address that does not exist on the domain, the email is forwarded according to postfix's alias setting in
# postmap -s /var/spool/postfix/plesk/aliases|grep bounce
