Oh well. I was hoping there'd be an easy way to find out. But I was mainly trying to use this for email. I already have sendmail set to block connections that can't be reverse dns'd so I suppose I could fairly reliably put a domain name in the access file to block email from the whole domain. This should work, shouldn't it? Relay hosts can't be forged unless a spammer controls them too, correct? -- redhat-list mailing list unsubscribe mailto:[EMAIL PROTECTED]?subject=unsubscribe https://listman.redhat.com/mailman/listinfo/redhat-list
