here's my summary of this issue that scott has been preseverating on for
the past year and a half or so:
-the RFC says MX records can't point to CNAMEs
-scott thinks that is silly and doesn't understand why it should be
-others point out that this was originally due to fears of efficiency
(multiple lookups for the same record).
-scott says: 'oh yeah? it's not that inefficient and so are other things
anyway'.
-others say: then change the RFC to be compliant
-scott says that we should ignore rfcs rather than update them.
-people generally stop taking scott seriously.
i've heard this conversation several times on the list so far and it
always goes like this. am i missing the ways in which this is a productive
conversation for anyone?
