I am to lazy to look it up right now but version i nthe 6.2 range was broken if it was upgraded to the 6.3 this should go away. I am using a pix on 6.3 and do not have the issue. On the altering data I have actually sniffed this before because I thought the same thing but the pix is not altering data it just looks at each packet and only allows what Cisco security group considered to be valid mail commands and screwed up the 6.2 code, this cause major issues with postfix also but upgrading to 6.3 has taken care of it for me.
So maybe if you recommend upgrading because of bad code on the pix the admin may take it a bit better and be willing to listen. -- http://www.digitalrage.org/ The Information Technology News Center ------------------------------------------------------- This SF.Net email is sponsored by xPML, a groundbreaking scripting language that extends applications into web and mobile media.
