0.10.0

CHANGES:

• Be able to compose errors from sendmail packages (@dinosaure, #76)

• Add the new package sendmail-mirage (@dinosaure, #77)

• breaking-change Improve the sendmail library.

  The sendmail library is able to send an email with or without STARTTLS. If
  the user gives an authentication method (with a password), we require STARTTLS
  in anyway. Otherwise, we return the Encryption_required error. By this way,
  the sendmail package does not leak such information.

  We also separate two kind of use about sendmail:

  • the submission of an email to an authority
  • how send an email to its destination

  The second is the most basic (and probably what you want). The first is useful
  when you want to pass through an authority (such as gmail.com or your own
  mail exchange server) to send an email to a destination.
