Indicates that the message that is being submitted from the command line is for relaying, not for initial submission. The message is rejected if the addresses are not fully qualified. No canonicalization is done. As is noted in the Release Notes that are part of the sendmail distribution on ftp://ftp.sendmail.org, improperly formed messages might be rejected in future releases.

-L tag

Sets the identifier that is used for syslog messages to the supplied tag.

-q[!]I substring

Processes only jobs that contain this substring of one of the recipients. When ! is added, the option processes only jobs that do not have this substring of one of the recipients.

-q[!]R substring

Processes only jobs that contain this substring of the queue ID. When ! is added, the option processes only jobs that do not have this substring of the queue ID.

-q[!]S substring

Processes only jobs that contain this substring of the sender. When ! is added, the option processes only jobs that do not have this substring of the sender.

-qf

Processes saved messages in the queue once, without using the fork system call, and runs the process in the foreground. Refer to the fork(2) man page.

-qGname

Processes only the messages in the name queue group.

-qptime

Processes saved messages in the queue at a specific interval of time with a single child that is forked for each queue. The child sleeps between queue runs. This new option is similar to the -qtime, which periodically forks a child to process the queue.

-U

As is noted in the Release Notes that are part of the sendmail distribution on ftp://ftp.sendmail.org, this option is not available as of version 8.12. Mail user agents should use the -G argument.
