Title: Add host config option to http_authentication plugin.

This is useful if the users are free to choose arbitrary mail hosts (or
from a list), but have one host they usually want to log into.

Otherwise the username/password must always be typed in twice.

I submitted the patch to the dev mailing list some time ago, but it seems to have slipped through:
