Does your desktop actually post outbound mail to internet mailservers directly? I.E. does it have its own Postfix or Exim or similar mailserver software that connects with port 25 on other mailservers on the internet? Or does it -- as I suspect -- merely have a mail client that sends outbound mail via an SMTP connection on another machine, that is, on an actual mail server?
I'm hoping you'll tell me you use an SMTP service at your ISP, or Google/Yahoo/Apple, or on your corporate network, or something like that.
But if your desktop is your mailserver, I'd say you are foolish because you're talking directly to other internet mailservers with your compiling machine, which is asking for trouble.
Which?
Up Yours seems to think EVERY computer should be screening EVERYTHING for EVERY potential malware on EVERY platform.
Yes, IT guys should be checking for it at sensible choke points.
No, end users shouldn’t be trying to eradicate the world of malware when they’re running suitably secured systems but other people insist on using long-promiscuous OSes.
