Can anyone tell me why Redhat's list server is rejecting my subscription
attempts, saying I must use a valid mail server?  I don't have this
problem with any other list I subscribe to.  I run my own mail servers,
but do not run my own reverse DNS.  Could this be the problem?  Even so,
why would Redhat be that paranoid?

Thanks

Because your DNS won't resolve.

Your mail server may handle mail for zonekeeper.org and harland-wolfe.zonekeeper.org, but only the 2nd one resolves, so if you use an address of [EMAIL PROTECTED] the problem should go away.

Getting there is only half as far as getting there and back.
