Not many I would guess.  A few months ago I was having a delivery 
problem and disabled TLS for qmail-remote.  Later on while it was 
disabled there was one domain that wouldn't accept mail without TLS. 
Surprised me when I saw it.  I didn't make a note of the domain.  I just 
took a brief look in the logs to see if I could find it but the details 
are dim now and I'm not finding it.
