[Dovecot] Auto Discard Vacation Sieve in a date

I have deploy an environment with pigeon sieve, managesieve, dovecot, squirrelmail and avelsieve plugin. The vacation messages are working fine. I am looking for a method to discard vacation messages in some date, when the user returns.

¿Has somebody looked in this feature?

Thanks a lot,
