%description
Exim is a mail transfer agent (MTA) for hosts that are running Unix or
Unix-like operating systems. It was designed on the assumption that it
would be run on hosts that are permanently connected to the Internet.
However, it can be used on intermittently connected hosts with
suitable configuration adjustments.
