uucp

Synopsis

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.

Note that the smtp delivery agent must be defined first if you want to use uucp-dom and uucp-uudom:

MAILER(`smtp')  ← define first
MAILER(`uucp')← define second
