Discovered on wikitech, when the server hostname is configured with a relative protocol, the mails sent are broken.
It should either default to a configuration variable, a user preference or whatever the request triggering the mail had as protocol.
The problem with the latter is that it results in inconsistent e-mail (ie. user John get's mixed urls in his emails, some http some https one of which he is mostly likely not logged in at)
