Does the 'SMTP HELO Required' setting also cover EHLO on my Barracuda Spam Firewall?

Solution #00001817

This applies to all Barracuda Spam Firewall models and all firmware releases.

Yes, when SMTP HELO Required option on the Advanced > Email Protocol page is set to Yes, either an HELO or EHLO will need to be issued when a mail server connects to the Barracuda Spam Firewall to transmit email.
