Upgrading to this version does not require any special efforts. You
can use your configuration files and filter scripts without any
changes. The only difference worth noticing is that starting from this
version mailfromd is always compiled with asynchronous
syslog implementation. The --enable-syslog-async
configuration file option is still available, but its meaning has
changed: it sets the default syslog implementation to use
(see syslog-async). Thus, it can be used the same way it was in
previous versions. You can also select the syslog implementation at
run time, see –syslog-async option, for
more detailed information.
