This user is out until...

Users->AddUser->Holiday

These three drop-down menu items allows a date to be set up to which this user is not expected to collect their e-mail. Once set up, all e-mail arriving for this user will result in an automatic e-mail being returned to the sender.  The body of this e-mail will contain the phrase set as the Out Message phrase.

No further automatic responses will be made on or after the set date has been reached.
