How NOT to solicit my business

Okay, our Lotus licensing is up for renewal, and I received the info from IBM the other day. Just yesterday I received an email from an IBM Business Partner that wanted the opportunity to quote us for the licensing. I figure that’s fine (since I have the requests for quotes out to a couple of other companies) so I hit reply, and send the person an email with the appropriate information for the quote. Later I get an email rejection:

SMTP Protocol Returned a Permanent Error 553 sorry, that domain isn’t in my list of allowed rcpthosts (#5.7.1)

Well, if I can’t send you mail, then I guess you can’t quote me. Good business model there…
