I'm not sure that's the problem. We only greylist mail which actually looks suspicious in the first place -- if it isn't HTML and doesn't have any SpamAssassin points (and doesn't offend in a bunch of other ways) then it wouldn't get greylisted. And if if _was_ greylisting, then the first time your mail host is seen to actually retry and get the mail through then we'll never defer mail from that IP address again.
I don't see either of those connection attempts in the logs for canuck.infradead.org. Canuck is on GMT-5, and I've looked in its logs for a few minutes around 08:27 and around 06:49. Nothing seems to match your sender address.
I suspect your mail host isn't even _trying_ to make an SMTP connection; perhaps because I publish IPv6 addresses for each of my MX hosts. I've seen that kind of brokenness from Postfix in the past -- what MTA are you using? If you claim my mail server rejected it, please show the rejection message.
Please show your own mailserver logs with the alleged delivery attempt. Here's mine from canuck (with _valid_ incoming mail elided). Although in fact you should have been delivering to pentafluge.infradead.org in Arjan's case, not canuck. I don't see anything relevant in pentafluge's log either.
