Is there an RFC *requirement* for reverse dns?
No.
I've been looking through the RFCs and I can't find it.
Right.
Some folks think reverse dns should be completely disabled.
I wonder if these are the same folks who ignore most other best practices.
I know for sure that this will break email, because many mail servers won't talk to a server that doesn't reverse.
For this reason, it is recommended (by me and many others) - but not required - to implement valid reverse DNS for the IP addresses of your SMTP servers. [..]
I'm also looking for a list of things that *break* when you disable reverse (e.g. mail).
Why disable it?
RULES FOR RESPONDING: 1) "Reverse is a good thing" is not an answer. Neither is "Reverse is a bad thing".
Check.
2) Opinions are not useful - stick to facts only - chapter and verse please.
2 out of 3.
3) All replies to the list please - others will find this useful as well.
3 out of 3. Time for me to pick-up a lottery ticket. ...D _______________________________________________ Full-Disclosure - We believe in it. Charter: http://lists.grok.org.uk/full-disclosure-charter.html Hosted and sponsored by Secunia - http://www.secunia.com/
