It turns out that "due to some postfix change" (whatever that means; I don't do servers), most (all?) of my recent automated account creation emails have gone into the luminiferous ether. This has been going on for some weeks, now and I have erroneously ascribed the problem to spam-blockers.

Anyway, thanks to Jamez for letting me use him as a guinea pig and to Jeremy Howard at fastmail.fm for digging through server logs in an attempt to get to the bottom of this.

And my sincere apology to all of those who have patiently (and vainly) awaited for a response from me on getting their trial accounts going.

If you've sent a request prior to today and haven't received a response, please let me know by email to chatsw@mailcan.com.

Best regards to all,

Marc
