Hmm. I've found some Cisco docu that seems to indicate it's a
feature:
http://www.cisco.com/univercd/cc/td/doc/product/iaabu/pix/pix_62/config/fixup.htm

I guess I'll have to read some more to figure out how to turn the
feature off, though. There's nothing I can see in the config that's
explicitly enabling the EHLO mangling, but certainly the description
here matches what I'm seeing.

Thanks for the pointer!

Cheers,
Waider.
