Not sure. Vacation code is not changed since... first release sieve plugin.

Vacation code calls 2 functions: first marks dupes (it seems working) , 
then, if it success second function is called which actualy sends 
vacation message. This action (success or failure) is loged in log file.
1. wthat is in your log files?
2. the only reason I can guess about failure in second function is 
sendmail binary.  default value of "sendmail_path" (hardcoded) is 
/usr/lib/sendmail. You can verify this:  "strings 
/path/to/dovecot/deliver | grep sendmail" If default value is incorrect 
try add sendmail_path variable in dovecot.conf
e.g.:
-----
 protocol lda {
   sendmail_path = /usr/sbin/sendmail
   ....
 }
-----

..anyway I recommend upgrade to 1.0 release at less.
