server2.centralsoft.org, localhost.centralsoft.org, , localhost

<Ok> <Cancel>

The listed domains will appear in your main.cf configuration file.

If not forced, then there is a remote chance of losing some mail if the

system crashes at an inopportune time, and you are not using a journaled

filesystem (such as ext3).

The default is "off".

Force synchronous updates on mail queue?

<Yes> <No>

Because nearly all current distributions use the ext3 journaling filesystem by default,
