Incorrect.

The HELO/EHLO string is NOT _required_ to be anything.  It SHOULD (not MUST)
be the FQDN of the connecting machine.

A 'liberal' mailserver should/would accept that string.

Many/most mailservers do enforce a requirement that the string be a _valid_
domain name -- above what the RFCs require -- as an anti-spam measure, and
that string is NOT valid a domain name, either today or when your software
was written.

There should be an option in Post.Office to turn off that check -- I don't
know Post.Office well enough to say what it is, however.
