Call sendmail with to not recipient
After the refactor f7a57c82 the server.sendmail line was not updated to now send the to the email address but instead sends to (email, 'en') and as sendmail accepts an iterable an email is also send to 'en'.
Due to an influx of spam, we have had to temporarily disable account registrations. Please write an email to accountsupport@archlinux.org, with your desired username, if you want to get access. Sorry for the inconvenience.
