We are using gnarwl for vacation notification and I would like gnarwl to only reply if the current time is in the vacationStart vacationEnd window.

Here is the queryfilter to do that using the following information:


$recepient - receiver of the message
$time - current time in seconds since the epoch
vacationActive - attribute for start time of the vacation in seconds since the epoch
vacationEnd - attribute for end time of the vacation in seconds since the epoch
mail
mailAlternateAddress - attribute for email address of an account


queryfilter

queryfilter (&(|(mail=$recepient@*)(mailAlternateAddress=$recepient@*))(vacationActive=TRUE)(|(!(vacationStart=*))(&(vacationStart<=$time)(vacationEnd>=$time))))

Broken down this does the following:

(&
(|
(mail=$recepient@*)
(mailAlternateAddress=$recepient@*)
)
(vacationActive=TRUE)
(|
(!(vacationStart=*))
(&
(vacationStart<=$time)
(vacationEnd>=$time)
)
)
)


There's a few things going on here.

Check that all these conditions are met (that is the outer and (&).

• Match either mail or mailAternateAddress on the recepient address
• Make sure vacationActive is TRUE
• Check that either vacationStart is not present or
  • vacationStart is less than the current time and
  • vacationEnd is greater than the current time.
