Re: [cobalt-users] redundant mail-servers

[Jim Roberts <jim@xxxxxxxxxxxxxxx>]

Jeff:

What do you mean by redundant email servers?

a.) Two copies of each email, available from different pop accounts?
	(If one POP server goes down, there is a copy of each message...)
b.) Two MX records, pointing to two different servers, one of which is the
	delivery server?
	(If the delivery server goes down, the other one holds the mail until
	it comes up again...)
c.) Something else?

Your questions below:
1.) I don't know.
2.) I would say I have been asked for "high availabiltity," rather than
redundancy.
3.) My answer is two MX records like in (b) above, on geographically
separate servers.
