This is mostly not a Postfix issue, and really needs to be taken up
with the provider. However,
You need to clearly understand the difference between a submission
service and normal (to MX) SMTP delivery.
It seems that you're trying to send email *from* a sender address
that is at the provider's domain (and this would typically involve
authenticated submission) *to* a recipient address at the provider's
domain (which under normal circumstances goes to the provider's MX
host).
Generally, given a working SASL configuration and a correctly
working submission service, the submission aspect takes
precedence, and all mail sent with that sender address
(possibly via sender_dependent_default_transport) should
use submission. So port 587 is not necessarily wrong,
but you do need a correct username and password, and
a working submission service that is willing to accept
your traffic. At least one of these is not working, not
much Postfix can do about that.
You should perhaps first test with an MUA (Thunderbird or
similar) and find a working submission service, and only
then proceed to try to duplicate the same settings in
Postfix.
