Resolution
-
Connect to the server via RDP.
Note: if direct RDP access to the server is not possible, contact server administrator for further assistance.
-
Go to MailEnable Management > Messaging Manager > Post Offices and check whether postmaster user exists under localhost domain. If postmaster user absent:
2.1. Delete localhost domain from MailEnable Management.
2.2. Disable and enable option Use the mail server installed with Plesk and the default mail account created by Plesk in Plesk > Tools & Settings > External SMTP Server.Note: Domain with postmaster@localhost will be recreated by Plesk automatically.
If for some reason use of postmaster@localhost is not suitable, then make sure that 127.0.0.1
is set in Host name or IP address in Plesk > Tools & Settings > External SMTP Server.
