Just a guess, but since you've got fail2ban running, have you checked to see if you accidentally banned your IP address when testing? I've done that before. I'd suggest double-checking the fail2ban log to see if your IP address is listed, and/or make sure it's whitelisted in your fail2ban config. If that's not the problem though, then I'm not sure what's going on with Postfix...
