Do a restart rather than a reload. A reload just tells MailScanner to 
re-read the config files, it doesn't restart either of the sendmail processes.
Even better do a stop, then a
         ps ax | grep -i mail
to check that everything really did die, then a start.

You're not the first, and probably won't be the last. I've managed to
