Hi cuongtl
are these smtp-auth error messages? If you don't need smtp-auth, you can disable it system-wide. enter the following commands in the console:
config system mailserver set smtp-auth disable set smtp-auth-over-tls disable set smtp-auth-smtps disable endSelect Forum Responses to become Knowledge Articles!
