I think you need to examine normal installs and performance here. While
the ODBC portion may not have a problem moving 100 records a second,
quite a few DBs have problems when you do that kind of insert load on
them. Specifically I would never bet the farm on MySQL holding up to
that. I would probably still be uneasy suggesting that Postgres would do
it on the hardware most people would send it's way. 

Don't take this as a disparaging thought about ODBC, just wanting to
bring some reality back to the questions.

Could you use the proper two dashes and a space for your sig delimiter.
It makes it so that most decent mail apps will automatically strip it
and anything after it during a reply. Not to mention it is a standard.
