Or the highly likely scenario that the primary gateway accessible to the survey tool is some load balanced SPAM filtering cluster, and not the MTA in use as final delivery.

Some of you may recall back in late 2006 we ran an international poll on MTA's, where over a period of several months and 12 and half thousands voters later, Sendmail was declared king, followed by Qmail, then Exim then Postfix, Exchange and some lesser know immaterials ...
Your survey has a gaping flaw I'm afraid. For example, 100 nameless people click on the Sendmail button because it came free with FreeBSD, versus those of us who have fleets numbering the thousands of Exim servers and he only gets to vote once. Oh dear...
Also, what about situations where there's multiple kinds of MTAs running in a network?
