My shop outlaws use of MS clients so I don't see this problem. (We use 
Thunderbird or its equivalent in the Moz suite. And I personally am using 
Mulberry.) Is this bug part of Outlook or Outlook Express, or does the 
machine lack a domain name (as set by DHCP)?

I think I'd like a MD recipe that identifies violations from outsiders and 
logs them. This should probably go in filter_end right after the spam 
determination. (No point in logging real spammers. I just want to see the 
FP's. Or at least identify the error variants with their ham/spam 
classification.) (I don't see a recipe on the wiki for EHLO-checking. I 
need to dig back through the archive to see how to pass the value from 
filter_send to filter_end.)
