localhostIPv4 and IPv6 addresses are not added in server white list.
- Ensure that
localhostIPv4 and IPv6 addresses are both whitelisted in Plesk:
Plesk > Tools & Settings > Mail Server Settings > White List tab > Add Network. The following IPv4 should be added for a localhost: 127.0.0.1. The following IPv6 should be added for a localhost: ::1/128
- Connect to the server using SSH/RDP.
- Add permit_mynetworks parameter into the smtpd_recipient_restrictions in
/etc/postfix/main.cf. By default it should be:
smtpd_recipient_restrictions = permit_mynetworks, permit_sasl_authenticated, reject_unauth_destination
- Reload postfix:
# service postfix reload
IPv4 and IPv6 addresses into the white list makes it impossible to use Outgoing Mail Control.
Outgoing mail messages sent from IP addresses that are not in the white list are still processed by mail handlers.
