How to Run a Subset of the Mail Queue, /var/spool/mqueue

Use this procedure, for example, to force a substring of an address, such as a host name, to be processed. Also, use this procedure to force a particular message from the queue.

1. Become root or assume an equivalent role.

   For information about roles, refer to “Using Privileged Applications” in System Administration Guide: Security Services.

2. Run a subset of the mail queue at any time with -qRstring.

   # /usr/lib/sendmail -qRstring

   string

   Use a recipient's alias or a substring of user@host.domain, such as a host name.

   Alternately, you can run a subset of the mail queue with -qInnnnn.

   # /usr/lib/sendmail -qInnnnn

   nnnnn

   Use a queue ID.
