what email client do the recipients use?


i tried it with 2 different ones:
one correspondent has Outlook Express, the other has Hotmail


does the recipients get a message large enough to indicate the attachment
is present but hidden?

no, the receive a small mail

if so, the messages are getting converted to rtf formatting.

no, that's not the case
