The problem is that seemingly only one or two spam emails from an IPv6 address seem to trigger their automatic filter and cause it to reject further emails from the entire/64 block to be rejected due to an "unusual" amount of UCE. Of course it's not all that unusual, since I have a few customers who forward their incoming email to Gmail and occasionally a spam email slips through my spam filters. What's really annoying is that a) the filter is on such a hair trigger (I have no such problems on IPv4) and b) there seems to be no way of getting Google to adjust their filters. Has anyone been successful in getting through to Google and having an IPv6 block permanently unblocked?"

So I wrote a little web tool for myself and some colleagues, which is now open to the general public. Just enter an email address (the left part really doesn't matter, it's just so it's more end-user friendly) and the tool will tell you which MXs accept email for the domain and if they support TLS. Of course you still need to be sure that you support it on your end as well... try it at http://www.ismymailsecure.com/
