I just installed XEAMS and followed the instructions to install in firewall mode. Live monitoring is on and it is accurately categorizing SPAM. I can receive mail, but not send. Please see the following:

<-- 250 2.1.0 Sender OK

--> RCPT To <xxxxx@gmail.com>

<-- 530 5.7.0 Authentication required

--> QUIT

Status: 5.7.0

Action: failed

This is happening to all outgoing mail.
