1.35 -Exim may be configured to listen on both IPv4 and IPv6 interfaces, even in environments

1.42 +=== Authentication ===
1.43 +
1.44 +It is highly undesirable to allow anyone to connect to a mail server to send
1.45 +mail. However, it is highly convenient to allow imip-agent to connect to the
1.46 +mail server on the same host without having to provide credentials. Consequently,
1.47 +the configuration of an MTA must permit the latter without allowing the former.
1.48 +
1.49 +Fortunately, many MTAs are configured to allow local connections because programs
1.50 +typically rely on such traditional behaviour, but this may be worth checking if
1.51 +mail server logs indicate authentication failures when imip-agent is attempting
1.52 +to send mail.
