When the remote site comes back up, you
can later process the files in that other queue by running sendmail withan artificially long
Timeout.queuereturn value (?§11.9 on page 436).

11.12 The qf File Internals | 457
A second way to extend the life of messages in the queue is to edit the qf file and change
the value stored in the T line. Just add 86400 to that value for each day you want to extend.
Care is required to avoid editing a file that is currently being processed by sendmail.*
There is currently no plan to give sendmail the ability to rejuvenate queued messages (make
old messages appear young).
The form of the T line in the qf file is:
Tsecs
The T begins the line, and the secs must immediately follow withno intervening space. The
numeric text that forms secs is converted to an integer using the C-library routine atol(3).
That routine allows secs to be represented in text as a signed decimal number, an octal
number, or a hexadecimal number.
If secs is absent or the entire T line is absent, the time value is zero. A zero value causes the
mail message to time out immediately.
There should be only one T line in any qf file. Multiple T lines cause all but the last to be
ignored.
