Re: [mailop] verifier.port25.com
As a postscript to this, I was formerly employed by SparkPost and so still have some contacts with people associated with Port25. When this thread kicked off yesterday, I noticed that the DNS for verifier.port25.com was a bit wonky; specifically, the MX record for that name resolved to "verifier." I reached out to my contacts, and they corrected the DNS. I don't know if that fixed the issue that led to the creation of this thread, but verifier.port25.com might not be down after all.

Sorry for the shameless plug, but my product, EmailEngine.app has this built-in and also supports running these tests automatically with an API call.
