Definitely NOT. Inbound mail and outbound mail are often handled by
different servers, sometimes completely independent organisations.
Since your problem is only in the outbound direction, you only need to
change your "relayhost". You can and should continue to receive inbound
mail on your own SMTP server. PTR records are not needed for that.
For outbound mail, if you have any SPF records, you need to make sure
that any "relayhost" is listed in your SPF records.
