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.
Except Xtra's mailservers were in the headers, so unless the virus knows how to forge those, I don't think so ;-) Regards, Simon (Besides, Des just pasted the output from their virus scanner log showing it) - To unsubscribe from nznog, send email to majordomo(a)list.waikato.ac.nz where the body of your message reads: unsubscribe nznog
