Re: So cool a flash,enjoy it

From: "Simon Byrnand" Besides, I recieved warnings from other peoples virus scanners, not Xtra's. Among them were "Marshal Integrated McAfee Antivirus", and "InoculateIT Ver 6.x".

For other peoples virus scanners to pick something up, then Xtra's - bydefinition - must have let something through. Whether what got let through was dangerous or not is another matter.

Xtra didn't let it through, their servers probably never saw the message. I gather Klez has its own SMTP Engine and may choose to send direct rather than using the configured SMTP parameters. Thus some infected messages would bypass Xtra's outgoing SMTP server. To trap all outgoing viruses the ISP needs to run an invisible SMTP proxy, or the onsite firewall should trap/redirect all outgoing port 25 sessions to the ISP's SMTP smarthost.
