WHM Not Allowing To Connect To Smtp Using Root Domain – CPanel

i am trying to connect to smtp server but not able to connect .
its giving the following error.

Failed to authenticate on SMTP server with username “[email protected]” using 2 possible authenticators.

all password and setting are right.
think so some problem with WHM.

also when i turn Restrict outgoing SMTP to root, exim, and mailman (FKA SMTP Tweak) [?] to ON it dosent work.

but when i turn Restrict outgoing SMTP to root, exim, and mailman (FKA SMTP Tweak) [?] to off it works but send mail from localhost .
