I don't know if their MTA is currently having problems, but it took my MTA 12 minutes to deliver the message to theirs. When I telnet to them on port 25 the welcome banner doesn't seem to appear. If they're using some form of artificial delays or greylisting, that's all well and good, but it's not really suitable for this sort of service. I imagine a lot of people would get bored of waiting and just leave.
