Time values in sendmail
To set the message timeout and queue processing interval, you must use a specific format for the time value.
The format of a time value is:
-qNumberUnitwhere Number is an integer value and Unit is the unit letter. Unit can have one of the following values:
| Item | Description |
|---|---|
| s | Seconds |
| m | Minutes |
| h | Hours |
| d | Days |
| w | Weeks |
If Unit is not specified, the sendmail daemon uses minutes (m) as the default. Here are three examples illustrating time-value specification:
/usr/sbin/sendmail -q15dThis command tells the sendmail daemon to process the queue every 15 days.
/usr/sbin/sendmail -q15hThis command tells the sendmail daemon to process the queue every 15 hours.
/usr/sbin/sendmail -q15This command tells the sendmail daemon to process the queue every 15 minutes.
