Hi we keep seeing this type of message on our firewall logs; Im not 100% sure if it's anything to worry about (is it just a SMTP command the PIX doesn't know?)
Critical 192.168.1.1 %PIX-2-108002: SMTP replaced l: out 212.125.75.19 in 192.168.1.25 data: MAIL FROM:<emailaddresses@mail.com>..
This is a Mail Guard (SMTP) message generated by the fixup protocol smtp command. This message is logged if the PIX Firewall replaces an invalid character in an email address with a space.
Recommended Action: None required.
