Because RFC says, that client have to introduce itself by own (FQDN) host name
in HELO/EHLO command. Before you complain, try to learn something about the
subject.

But that is not the real problem, real problem is, that you are using SMTP port, not the
Submission(S) one... And many MTA, including my, will filter (beside other rules) bad
HELO name on SMTP port nowadays.
