>except for possible "end of line" conversions ( CR to CR LF ).
The message is sent from a PC running MS Express and is received by an IBM PC Machine running MS Express. So I believe there shouldn't be any eol conversions, I believe the corruption is occuring on the reception as I have tried sending out the E-Mail on a IBM PC E-Mail Server to be received by TF MailServer. So trying to eliminate MailServer from the transmission side of the equation.
I have also viewed the MS Express newsgroups in case there is some problem with receiving signed messages, as of yet there have not been any.
Can I send you a digitally signed message to be received on some test account that might help.
