Anyone have a clue?

Microsoft Outlook has been a longstanding issue with this behavior.
As for changing the settings, here's how I usually do this.   The postconf -e command shown over in that earlier thread will likely require tweaking as Mavericks has moved the configuration file.   You'll need to add the -c switch with the current configuration file location to the postconf command, as Server.app has stashed away its own copy of this file.
sudo postconf -n -c /Library/Server/Mail/Config/postfix
sudo postconf -c /Library/Server/Mail/Config/postfix -e "smtpd_helo_restrictions = permit_sasl_authenticated reject_invalid_helo_hostname reject_non_fqdn_helo_hostname"
Which will allow (only) authenticated users to bypass the HELO checks.  What's shown here also differs from that earlier thread as I'm not allowing unauthenticated local access here.  Then restart the Postfix server with:
sudo postfix reload
I'll report that article to the  hosts.
