Jeff Atwood talks about this: http://blog.codinghorror.com/so-youd-like-to-send-some-email.. http://blog.codinghorror.com/so-youd-like-to-send-some-email.... . And its unlikely that the code takes care of all these things. For example, how are you going to configure the reverse ptr in code?

- josho 13y agoWith dkim/SPF the lack of a reverse ptr is less important. I've had one email bounce as a result, even then the bounce included instructions to resolve the issue with their server.
- mike-cardwell 13y agoEven if it can't set the PTR it's self, it could at least detect if your PTR is missing or wrong, and display that information to you with some advice on how to resolve it and how important it is.
- joshdata 13y agoThanks for the idea! I've added a test for PTR: https://github.com/JoshData/mailinabox/commit/ec11241a7a619a9d9cafb7696e96592b45dbf7b5 https://github.com/JoshData/mailinabox/commit/ec11241a7a619a...
- haroldp 13y agoYou might also: * Test/alert if your PTR mismatches your HELO name * If your IP is on any of the major RBLs * Point admins toward AOL/Yahoo/ReturnPath whitelists and feedback loops.
- btgeekboy 13y agoAdditionally, you should test whether your PTR "smells" dynamic (i.e. contains part of your IP address in the PTR itself.) It may or may not be something within your control, but you should know as it may cause you problems later.
