Depends on your OS... I don't know is this path correct for you.

and here is answer to your problem: "execv(/usr/lib/sendmail) failed: 
Permission denied" - fix this. Dovecot deliver tries to execute sendmain 
binary "/usr/lib/sendmail" and got "premission denied" error form OS.

This means  - not only "vacation" is not working on your server - 
dovecot also can't send bounces, forwards and notify messages.
