[RFCI-Discuss] is a reversename a must ?

[Andreas Schulze]

hello,

I found, that rejecting mails from systems without any reverse name reduces my spamvolume drastic.
( in these days ... )
Is there any RFC which requires a system *MUST* have any valid reverse name ?

I looked up the rfc database but found nothing or too much ;-(


thanks
A.Schulze
