@amcotech - Did my answer, posted a day prior to Sunnyc7's not answer your question correctly?  Either I am going blind or mine clearly states the command is either:
HELO mail.yourdomain.com or
 EHLO mail.yourdomain.com

Alan Sorry - I have not been on EE for a while.
I am just checking good answer Alerts or 1/2 questions.

I think points should have been allocated to Alan as he got it first.
