Contact form doesn't work from own domain email on Godaddy - Joomla! Forum - community, help and support

i've read lot of threads here problem , none of them worked me.

i'm on dedicated server @ godaddy, , when set email myname@mydomain.com in contact component, doesn't work. when set email else, sends email it.

the thing owrks me submit emails when smtp host set localhost.

mailer
mail from
from name
sendmail path
smtp authentication no yes
smtp username
smtp password
smtp host

anybody have clue?

so doesn't work when set email use php within global config? use "php mail function" within joomla global configuration > server > mail

this requires php_mail function turned on within php settings on dedicated server typically should on default.
