This really has nothing to do with Cygwin.  In windows there is a
"global" domain name and then a "connection-specific" domain name for
each connection, and these are all set in the "Network and Dial-Up
Connections" thing under TCP/IP properties.  The "global" domain name
you may have to set in the registry as it's probably not set by Windows
unless you're a member of a domain.  Also, the DHCP response (if
enabled) can also contain a domain suffix that windows will try to use. 
You can see all of this if you run "ipconfig /all".  

As far as OE goes, who knows what it uses in its HELO string, but I'd
imagine that if you have either a "primary DNS suffix" or a
"connection-specific DNS suffix" that it would use one of those.
