Hello Sluggers,
I am being forced to use "that other OS" in a project, and I had a
question about email malware protection. Now that I think about it, I
think it applies to Linux too, especially if you are using Mozilla.
Obviously, if you are encrypting your email (with either gnupg or
S/MIME), the anti-malware on your mail server (and gateway firewall, and
gateway mail-server, all running different vendor's products) is
completely useless, since these applications can't peer into an
encrypted email just as everyone else can't.
My question is, "when does the /client's/ anti-malware check incoming
emails, before or after decryption by the mail client?
I would assume, since Outlook supports S/MIME out of the box, that virus
scanners that integrate with Outlook would look as soon as the email was
decrypted, before the user interacted with it... but I can't see the
source code to make sure. GPG4Win is not natively supported, so who
knows if it checks at all?
Ditto with Thunderbird... when does it check? With Thunderbird, I am
especially worried about people sending infected /files/, not embedded
macros. If someone gets an infected /document/ in the mail, they may
open it (or put it on a server) /before/ it is scanned.
Any ideas?
I did a Google search, but did not find an answer to this question, and
I think it is worth asking.
