The Maxuuxqts (/usr/lib/uucp/Maxuuxqts) file contains an
ASCII number to limit the number of simultaneous uuxqt
programs running. This file has a default entry of 2.
If there is a lot of traffic from mail, you can
increase this number to reduce the time it takes for the mail to leave
your system.
Keep in mind that the load on the system increases with the number
of uuxqt programs running.
