Agreed, Steve, but I wasn't trying to *really* enumerate what they were using; the test was really more along the lines of "Fortune 100 SMTP Banners", but I didn't have the presence of mind to name it that at the time. :)

Thanks for the note...

Looking at banners doesn't answer your original question.

These responses:
220 ******00*******************************************0****0****0 **********************200**22****20 *0*00
Are typical of PIX. There's many others in the results file that don't identify a particular mail server.

Aside from that, to find out what they actually use, you should have sent an email that would bounce (or generate a reply of any sort), then examine the headers. Or, use a search engine to find postings to some mailing list from someone at the company in question and do the same thing.

Very interesting Daniel. I just found your blog, and really enjoy it. We cover many of the same topics. I added you to my blogroll too so I won't forget you. :)
