<br>Some time this week, Google started blocking 7zip encrypted archives (.7z).
<br>You can no longer send or receive emails which contain 7zip encrypted

<br>I haven't seen any announcement about this...nor any discussion, but it's
<br>causing us (as a Google Apps for Education "customer") pain.

<br>Google are, of course, only doing this for our protection. What other
