Remote emal servers

[doWhileSomething]

Hello,

I'm trying to set MX records for email/webmail that is hosted outside of plesk. I need to enter these records as domains, but Plesk appends the given(current) domain to all records. How can I enter an MX record without using the given domain.

e.g.
Domains >> Select domain >> DNS >> Add New DNS Record >> select record type (MX) >> enter domain - this is the problem (I think), as it appends the domain to the record (read only) and I can't change this.

For example, I need to enter smtp.secureserver.net - I have no idea how to accomplish this.

Thanks in advance for any light you might be able to shine in this.
