Vacation Sending To Root

Dovecot Version 2.0.9

I am having an issue where all vacation messages are being sent to root. Is any one able to advise.

Dovecot Log Shows :- Sieve: msgid=< CAMD5TViw0sSigGm8JY5WOv0ROs1UdCJFnvb9vo-RzcNN74E92Q@mail.xxxxxx.com>: sent vacation response to <root>

The emails are handed off to dovecot from sendmail using procmail

:0 w | $DELIVER

The variable $DELIVER is set as DELIVER="/usr/libexec/dovecot/deliver"

I do have DROPPRIVS=YES in procmail, however I don't think deliver works without this.

Any advice would greatly help.
