- Mail list is working correctly with mailboxes hosted on Plesk server.

example.com' fails with the following error in the:

localhost IPv4 and IPv6 addresses are not in White list in Mail Server settings.
localhost IPv4 and IPv6 addresses are both white listed in Plesk.
1. Go to Tools & Settings > Mail Server Settings > White list
2. Check whether it contain the following addresses: ::1/128 and 127.0.0.1.
localhost IPv4 and IPv6 addresses into the white list will fix issue with mail lists. But mails sent from
localhost will not be checked: neither webmail and php scripts nor mail lists.
Outgoing mail messages sent from IP addresses that are not in white list are still processed by mail handlers.
