Bug#787505: libnss3: NSS 3.19.1 breaks icedove IMAPS to server with DH 786 temp key

[Jean-Christophe Dubacq]

Package: libnss3
Followup-For: Bug #787505

I was bitten by this also. My imapd server was a rather dull courier-imap-ssl
server, and the DH key length was left as is since its installation (probably
etch). My config file was mostly untouched, and no warning came.

I followed the procedure here :
http://apple.stackexchange.com/questions/206448/imap-account-stopped-working-after-upgrade-to-ios-9-problem-with-cacert-certif?answertab=active#tab-top

and it worked fine.
