[RFC] DKIM header in emails

[naim]

Mails sent without DKIM have a very high probability to be caught by the recipient's spam filter.
phpBB doesn't implement DKIM in emails, I think it would be a very good idea if it would.
People that receive emails from the forum board will be able to see the the email was actually sent by the board, and nobody else.

The DKIM specification/docs can be found here: http://www.dkim.org/
DKIM on wikipedia: http://en.wikipedia.org/wiki/DomainKeys_Identified_Mail

DKIM should be optional, not everybody would be able to enable it (not everyone can manage DNS records, or have the ability to use TXT records).

I dont think this should be something to be done in php(BB), but should be done with the used MTA instead.

While it would not be impossible to add this feature to phpBB, the MTA indeed looks like a much better place to have DKIM.

but many people have mutualized hosting and can not change anything in the MTA, so it could be interesting to make a plugin

Yeah sure, feel free to make this an extension. But please keep in mind that DKIM also requires the ability to add DNS TXT records which is likely not possible either in most shared hosting environments.

I would think that DNS records is something you can nearly always edit, while MTA configuration hardly ever is.
