just a general question…
is it possible for two primary mail servers to act as backup mail servers for each other?
I am assuming its mainly just:
- registering the opposite server in webmin> “webmin servers index” on both machines and,
- a dns issue and having virtual domains on both servers where in dns the relevant domains point the secondary mxrecord at the opposite server as the backup?
is that correct?
Is this a reasonably satisfactory efficient use of the backup mail server (ie to also put virtual domains on it for web and email hosting?) Just thinking about the need for a backup mail server but also money saving i suppose…so if one could also use the backup mail server for hosting other domains…?
