IDSMail is a wrapper to send mails, like Nigel Coates MapiMail class. You would not say, that MapiMail is Default e-mail client, if your default e-mail client is Outlook Express, for example. My problem is that I want to be able to find it out.

BTW, once we switched to Outlook exchange, UT News letters start to come in incorrect format, e.g. I see nothing in the body of e-mail. I guess, I have to adjust some settings in Outlook, but haven't figured this out yet...
