uucp

Deliver using UUCP V8.1 and later

The UUCP delivery agents are used to forward email over UUCP networks. The following declaration enables six delivery agents (although two are synonyms for others, meaning there are really only four):

MAILER(`uucp')

The enabled UUCP delivery agents are shown in Table 20-16.
