Well you could try adding this into your rules.ima file F~(<>|<ok>):NUL
would dump any void senders or those whom use OK for there return. ~Rick Oh yea.. earlier post stated something to the effect to place a check mark into the 'refuse <> null senders' block. Some folks don't like this, I agree, for compliance.. -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]]On Behalf Of J.R. Dobyns Sent: Tuesday, June 18, 2002 3:05 PM - MGMT.TV To: Imail_Forum Subject: [IMail Forum] HELO and SMTP I read an article that some spam program's do not send a HELO or EHLO when they send out spam e-mails. The following outake came from and article in Security Focus on hints to block spammer's: "Some spam software does not send a HELO, and by using this option you may successfully block such bone-headed software." The following is the link to this article: http://online.securityfocus.com/infocus/1593 Thanks for all your advise, J.R. Do you have an example of what you are trying to eliminate. I can't see IMail accepting any kind of email conversation other than HELO or EHLO on the SMTP port Eric S ----- Original Message ----- From: "J.R.
