Fix the mail issues
There are several problems with the mail "system" and no real tests for it.
- its spam for many people
- google (as a recipient) says ''' firstname.lastname@example.org: host gmail-smtp-in.l.google.com[18.104.22.168] said: 550-5.7.1 [130.xxx.xxx.xxx 11] Our system has detected that this message is 550-5.7.1 not RFC 5322 compliant: 550-5.7.1 'From' header is missing. 550-5.7.1 To reduce the amount of spam sent to Gmail, this message has been 550-5.7.1 blocked. Please visit 550-5.7.1 https://support.google.com/mail/?p=RfcMessageNonCompliant 550 5.7.1 and review RFC 5322 specifications for more information. xxxxxxxxxxxxxxx.272 - gsmtp (in reply to end of DATA command) '''
- the email addresses are not consistent
- do we still need to send emails?
