SquirrelMail was updated to version 1.4.5, hopefully it'll be a bit more reliable now.
Also updated were:
dev-lang/perl-5.8.7-r3
net-proxy/squid-2.5.12
net-misc/curl-7.15.1
More to follow...
Mail is now backed up nightly to LS15 (currently at 04:30).
If you need something restoring let me know.
There's a whole stack of packages that need updating for minor security risks. I'm planning on making some progress on Saturday so some services might be unavailable for shortish periods.
