When outbound emails get blocked, this is an unusual case. Check the logs, and you will see a MUA flag. This represents whether SMTP authentication is being used. MUA=1 means that SMTP authentication is used, MUA=0 means that it isn't, or it failed in some mysterious way. Normally, when trying to send outbound, you have SMTP authentication, and many of the checks are bypassed, so as not to block oubound emails. If you find some that are being blocked, this is the first thing to check.
