Bug#941804: Seconded

[David North]

Yes please. I'd be happy to contribute a patch if the maintainers 
believe this is acceptable?

To expand on the original report: DKIM signatures are meant to 
authenticate various headers on a message regardless of what host(s) 
were involved in relaying it. So if one has gone to the trouble of 
setting up DKIM signing, and then has to swtich from direct delivery to 
smarthost, it's surprising/unhelpful that the DKIM signatures are no 
longer added.

Thanks,

David
