No. I repeat again. Filter based on just HELO is bad. I would suggest Suresh you also don't use it. Come on Suresh, you mean to say I on dial-up cannot send you any mails. That is bad. > A clear PERMFAIL 5xx is issued. What do you mean the mail is denied but > not bounced back? I think the mail is *rejected* at SMTP level so no question of bouncing it back.

You mean it will connect to my domain and actually use the VRFY verb to check if my email address / username exists? My MTA would NEVER allow that. If it did it would be a bonanza for spammers just verify address and do it. I think no modern MTA should ever do this.
