There are two ways to schedule a mailing:
You can schedule a mailing by clicking on the "Schedule" button located in the lower right corner of a Mailer window:
This brings up the scheduler window:
Note that if the computer is sleeping prior to the launch time of a scheduled mailing, Mailings can wake it up to commence the mailing provided it is running with "root permission."
You can also schedule a mailing as follows:
If the pathname of a Mailings document contains the string "SendOnOpen" then Mailings will immediately commence sending the mailing when the document is opened. This means that all documents placed inside a folder named "SendOnOpen" will commence when opened.
The purpose of this feature is to provide an alternative mechanism of scheduling a mailing. In particular it facilitates using Mailings with any other program which can launch documents at specified times, such as the utility LaunchOnTime.
