I'm assuming your talking about the mail server here ? I rather not mess with the mail server - lets just assume I don't have control of it - but in anyway its not local to the network with the private server on it, so I don't want to white list anything. > PS Why do try to resolve domains in the first place?

Lets assume I don't have control of it. But more to the point - its not checking for MXs. Sending mail or receiving mail doesn't require an MX. mail to [EMAIL PROTECTED] is valid even if yada.blabla.something.com does not have an MX record, as long as the domain itself resolves to an IP address. > If you are checking just for valid domains, i.e. with a valid A > records then again, what exactly will this check tell you? > Weigh carefully the overhead against the results. Its a form of enforcing correct behavior, its rather useful against spam droids and other fake e-mails. I actually can't see how any self respecting postmaster would use an unresolved name as a the domain in a >From address. -- Oded ================================================================= To unsubscribe, send mail to [EMAIL PROTECTED] with the word "unsubscribe" in the message body, e.g., run the command echo unsubscribe | mail [EMAIL PROTECTED]
