Wait ~ 1h until the mirrors catch up, then CVSup and compile with
LOG_FILE_PATH=/var/log/exim/%slog or WITH_AUTH_RADIUS=yes. Be aware
that `rejectlog' is hardcoded in 460.exim-mail-rejects, so it won't
work if you use a different name. An empty /var/log/exim is created
(and required) when you do LOG_FILE_PATH=syslog, but this should be
no issue.
