I didn't time it. Downloading the zone files was the hard part.

> the problems encountered,

Well, the MTA isn't always obvious from the greeting line and HELP
response. Here are my current guesses:

  /Microsoft Exchange Internet Mail Connector/ { ++exchange; next }
  /NT Server running Internet Shopper/ { ++ntmail; next }
  /Simple Mail Transfer Service Ready/ { ++smtsrfoo; next }
  /send comments to qmail@pobox.com/ { ++qmail; next }
  /CommuniGate SMTPGate is ready/ { ++communigate; next }
  /Apple Internet Mail Server/ { ++aims; next }
  /post.office E-mail system/ { ++postoffice; next }
  /TGV.MultiNet SMTP server/ { ++tgv; next }
  /MailSite SMTP Receiver/ { ++mailsite; next }
  /Worldgroup SMTP server/ { ++worldgroup; next }
  /Generic SMTP handler/ { ++raptor; next }
  /Netscape Mail Server/ { ++netscape; next }
  /EMWAC SMTP Receiver/ { ++emwac; next }
  /GroupWise SMTP.MIME/ { ++groupwise; next }
  /MetaInfo Sendmail/ { ++metainfo; next }
  /IMS SMTP Receiver/ { ++ims; next }
  /running MailShare/ { ++mailshare; next }
  /ListSTAR Package/ { ++liststar; next }
  /TGV MultiNet V/ { ++tgv; next }
  /AltaVista Mail/ { ++avmail; next }
  /Lotus SMTP MTA/ { ++lotus; next }
  /MX V.\..-. VAX/ { ++vmsmx; next }
  /post.office v/ { ++postoffice; next }
  /Connect2-SMTP/ { ++connect2; next }
  /MX V.\.. VAX/ { ++vmsmx; next }
  /MX V.\.. AXP/ { ++vmsmx; next }
  /Zachariassen/ { ++zmailer; next }
  /Pony Express/ { ++pony; next}
  /SMTP.OpenVMS/ { ++openvms; next }
  /IBM VM SMTP/ { ++ibmvm; next }
  /NASTA Gate/ { ++nasta; next }
  /SMTP.smap/ { ++smap; next }
  /Smail3.1/ { ++smail31; next }
  /SLmail95/ { ++slmail; next }
  /SLmailNT/ { ++slmail; next }
  /SLMAILNT/ { ++slmail; next }
  /Sendmail/ { ++sendmail; next }
  /PMDF V/ { ++pmdf; next }
  /SMTPXD/ { ++smtpxd; next }
  /IMail/ { ++imail; next }
  /Exim/ { ++exim; next }
  /UCX / { ++ucx; next }
  /The normal sequence of events in sending a message/ { ++normalfoo; next }
  /[pP][pP].*Pleased to meet you/ { ++pp; next }
  /Help \.\.\. Not recognized/ { ++helpfoo; next }
  /For more info use .HELP/ { ++sendmail; next }
  /unimplemented..#5.5.1/ { ++qmail; next }
  /Complaints.bugs to/ { ++mmdf; next }

I don't know what the smtsrfoo, helpfoo, and normalfoo MTAs are, and a
solid 2% of the responses don't match any of the above categories.
