The readme is referring to running 10 instances of the same content filter in parallel to increase performance.
You appear to be using the "simple" content filter method, where each filter reinjects mail to postfix by using the sendmail command. The normal method of chaining multiple filters by cycling through postfix won't work with "simple" filters (unless you set up a separate postfix instance for each filter). Since your OoO filter only applies to a single user, here's what I recommend... - modify your OOO script to pipe mail to your default content filter, rather than to sendmail. - use a check_recipient_access map that looks for the specific OOO recipient and calls the filter for them.
