Question on Fixup Protocol SMTP

In reading the Documentation, I understand that when smtp packets are inbound to the PIX, and fixup smtp is enabled, the non 7 commands are translated into XXX's. And it looks like the mailserver then recieved the XXX commands and replies with a 500 command not recognized.

What is not clear in my reading is does the PIX also look at smtp streams that are outbound as well and perform the same set of translations?

We are running 6.1.4 right now if the behavior of the PIX has changed from 6.1.4 to 6.3.x

Thanks.

Re: Question on Fixup Protocol SMTP

I believe the smtp fixup is in both directions.

Thanks
