They don't seem to be available anywhere I look, particularily not in the http://security.debian.org/ package repository or in the standard debian package repository neither for unstable nor for wheezy. http://incoming.debian.org/ has the versions indicated above, however the packages are not signed. What's the way forward from here? Will you rerun the incoming queue and build packages for security.debian.org or should users (blindly?) install the packages from incoming? I've set "DISABLE_DKIM_VERIFY='true'" to mitigate the bug in update-exim4.conf.conf but I'm not sure that's the way that flag is intended to be used since update-exim4.conf is complaining that it doesn't know anything about that configuration item. *t -- To UNSUBSCRIBE, email to debian-security-requ...@lists.debian.org with a subject of "unsubscribe".

Re: [SECURITY] [DSA 2566-1] exim4 security update
This is pretty serious and could easily cause some server hacks. Can we upgrade mail servers for just this issue more or less immediately? Please let me know what the status of the mailscanner server is.
