This looks to me like the receiving mail server has implemented a practice known as graylisting. The server rejects the first attempt with "unknown user", but then accepts a second attempt if it occurs within a reasonable timeframe later, like a minute to 20 minutes later. The idea is that spammers will just move on while regular mailservers will by default try again several times. So, you need to be in control of the mailserver you are blatting to, so you can accept all mail from your blat instance. Then relay that mail out to the receiving server on the Internet using a real smtp mail server, not merely a smtp client like blat.
