So, having multiple A records pointing to the same IP is ok then, when it
comes to MX?
like this:
IN MX 10 mail.swishmail.com.
$ORIGIN swishmail.com.
; Setup forward DNS for all hosts
IN A 63.165.246.3
www IN A 63.165.246.3
mail IN A 63.165.246.3
ftp IN A 63.165.246.3
pop3 IN CNAME swishmail.com.
Or should MX mail.swishmail.com point to an IP address that nothing else
points to? like for example:
IN MX 10 mail.swishmail.com.
$ORIGIN swishmail.com.
; Setup forward DNS for all hosts
IN A 63.165.246.3
www IN A 63.165.246.3
mail IN A 63.165.246.5
ftp IN A 63.165.246.3
pop3 IN CNAME swishmail.com.
The reason why I am asking is would mail.swishmail.com be considered FQDN
with the first example? Since mail.swishmail.com would resolve to
63.165.246.3, but 63.165.246.3 would resolve to swishmail.com. With the
second example, forward and reverse would give you mail.swishmail.com ->
63.165.256.5 and 63.165.256.5 -> mail.swishmail.com
