@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

Why You Should Analyze Threat Actor TTPs

After years of analyzing threat actor behavior, it’s become clear that at any given time there are specific tactics, techniques, and procedures (TTPs) that are particularly prevalent. By analyzing and understanding these TTPs, you can dramatically enhance your security program.

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.
