I assume it should be set to www
.mydomain.com since I don't have a computer labeled smtp or mailstore1, as opposed to the old target servers.
(I'm assuming this is meant to help the server accept incoming mails and will have no effect on whether or not I can log into squirrelmail. Is that correct?)
