Mailscanner digest detected as spam

[Bruno Melloni]

I noticed that SpamAssassin (with default settings) tags the MailScanner
list digest as spam.

Whitelisting jiscmail.ac.uk will solve the problem, but I thought I'd
mention it since it might be possible to do something to the list or
MailScanner defaults to prevent it.

SA score is 5.6 and the signatures are:

  MSG_ID_ADDED_BY_MTA_2
  CTYPE_JUST_HTML
