   HELO/EHLO

Question 

I recieved an email bounce notification stating, 550 Sorry, your HELO/EHLO greeting must resolve (#5.7.1)
What does this mean?

Answer 

This shows up due to a flaw in Outlook and Outlook Express, it is caused by the Fully Qualified Domain Name not being populated in the HELO field.  QWK.net servers check for the FQDN as a means to prevent SPAM.

To resolve this issue you can enter an FQDN in windows and the problem will go away.
