http://www.DNSstuff.com/tools/ptr.ch?ip=63.172.199.25 shows that you have lots of reverse DNS entries. Although it is legal to have multiple reverse DNS entries, there is no known reason to have multiple entries. That's because almost all programs that look up reverse DNS entries only use one of them (and usually assume there is only one reverse DNS entry). For example, someone you may have a Received: header like this in E-mail you send them: Received: from mail3.oldmanmurray.com [63.172.199.25 (mail.oldmanmurray.com)] by some.example.com with ESMTP (SMTPD32-7.06) id AEED4650206; Tue, 19 Mar 2002 19:59:25 -0500 If that mail server handled multiple reverse DNS entries, that same Received: header would look like (except that it would be about 5 times as long): Received: from mail3.oldmanmurray.com [63.172.199.25 (mail.oldmanmurray.com, email.evilemail.com, email.seanbaby.com, email.amish2000.com, email.crazygrandpa.com, email.fatbabies.com, email.shortandhappy.com,email.drunkenbastards.com, email.so-lonely.com, email.pimpdaddywelfare.com, email.zombieworld.com, email.evilportal.com, mail3.oldmanmurray.com, mail.amish2000.com, mail.bad-candy.com, mail.crazygrandpa.com)] by some.example.com with ESMTP (SMTPD32-7.06) id AEED4650206; Tue, 19 Mar 2002 19:59:25 -0500 That would like mighty weird, no? -Scott --- Declude: Anti-virus, Anti-spam and Anti-hijacking solutions for IMail. http://www.declude.com --- [This E-mail was scanned for viruses by Declude Virus (http://www.declude.com)] Please visit http://www.ipswitch.com/support/mailing-lists.html to be removed from this list.
