I'd guess the callout is timing out before their mailserver replies with the 220. Whether the delay on their end is intentional or not is anyone's guess (anti spam technique? Temporarily overloaded mailserver?)
If this is just happening with Kayako mails, then I'd agree, this is a Kayako problem. They frequently overload their mailservers, unintentionally or not. I've had this happen a number of times when doing business with them as well.
