Following up for those who may be curious...
I did email the support team with copies of the sent and received versions of emails. Glen correctly diagnosed the problem.
My email contained a line with exactly 76 characters, with last character ".", and followed by carriage return. Apparently, my Exchange server wrapped this line at 75 characters to put that "." all by itself on a line (with the carriage return).
The emails I received were being truncated directly before that ".".
This is a known bizarre issue.
https://unix.stackexchange.com/questions/38156/sendmail-procmail-exchange-truncating-mail

The answer there explains that
" - Exchange: on accepting a piece of mail for delivery, it appears to reformat a plain text message, encoding and wrapping its lines to 75 characters.
   - sendmail: An old (but known) behaviour was being followed in that mail with a bare period on a line was interpreted as end-of-message and then delivered, effectively truncating the actual mail body."

Well, I feel better now.
