Configure a non-email address login in External SMTP Server with the following workaround:
Connect to the server via RDP
- Start a command prompt as Administrator
C:> plesk db dump psa > C:psa.backup.sql
Set the non-email address login directly on the database:
C:> plesk db -e “update servicenodeconfiguration set value = ‘jdoe’ where serviceNodeId = 1 and section = ‘MailGate’ and name = ‘login'”
