That was an excellent tip.  I started looking closely at 
/usr/lib/sendmail and following the link chain.  Which led me back to 
/usr/sbin/sendmail.sendmail.

Which is probably not the correct sendmail binary to be using when we're 
running postfix.  Apparently, back when I setup this server many months 
ago, I never installed or ran:

# yum install system-switch-mail
# system-switch-mail

Which switches the links around to point at "sendmail.postfix".

Once I fixed that, I had to adjust SELinux properties to create a custom 
profile to allow the sendmail binary to do its work.

Thank you both for the pointers, everything is now working properly for 
vacation auto-responses.

(Oddly enough, the broken setup worked with Dovecot 1.0 - and only 
reared its head after we upgraded to Dovecot 1.1.)
