A client of mine told me that he couldn't send email to a particular address. The intended recipient's ISP is blocking the message.
After contacting the ISP in question, they sent me the following reply: > The reverse DNS entry on the server's IP should match one of > the server's forward DNS names, for example > "mail.netinteraction.com" or "mx1.netinteraction.com", so > that it can be easily recognized by other sites as a > legitimate mail server. Right now, the reverse entry is > "208-151-247-226.netinteraction.com", which is not very helpful. The host name for the Imail server is netinteraction.com, so my understanding is that this my reverse DNS is "by the book". I have two questions. The first question is how should I respond to these folks? Is there any merit whatsoever in what they are saying? Does anyone have a reference that I can point them to that clearly states why this is incorrect? The 2nd question is even if these guys are not respecting valid configurations, is there a "best practice" that would make my life easier when it comes to overzealous ISPs?
