Postmark docs notwithstanding, Postmark allows sending mail without a
To field, as long as there is some recipient in Cc or Bcc. The API
response has a slightly different shape in this case, and Anymail now
handles that.
Also updates related recipient status parsing. Previously, Anymail's
Postmark backend converted all recipient emails to lowercase for status
reporting, and omitted Cc or Bcc recipients from
`message.anymail_status.recipients[email]`. Now, the backend preserves
the case of each recipient email as originally sent, and includes Cc
and Bcc status.
Because client code may have been relying on lowercasing recipient
emails to check status, this is a potentially breaking change.
Fixes#135
Mailgun's API silently drops attachments without filenames (and inline
attachments without Content-IDs). Raise an AnymailUnsupportedFeature
error on attempts to send these attachments.
Fixes#128
Handle MIME attachments with Content-ID as inline by default.
Treat MIME attachments that have a *Content-ID* but no explicit *Content-Disposition*
header as inline, matching the behavior of many email clients.
Workaround requests/requests#4652 (urllib3/urllib3#303), where
uploaded files in multipart/form-data are improperly given RFC 2231
encoded filenames. That format is not accepted by Mailgun's API (and is
prohibited by RFC 7578), resulting in the attachments being silently
dropped.
Fix is to patch up the multipart/form-data before posting to remove
the RFC 2231 encoding.
Fixes#125
Optionally dump API requests and responses to stdout, to simplify
debugging of the raw API communications. Currently implemented only
for Requests-based backends.
This (undocumented) setting can log things like API keys, so is not
appropriate for use in production.
Use Postmark /email/batch or /email/batchWithTemplates APIs when
merge_data provided.
Parse Postmark batch-send API responses, and improve accuracy of
parsing individual recipient status from all responses.
Closes#122
Postmark issues an error if Django's default empty strings are used
with template sends.
Include template send in Postmark integration tests. (Requires real
Postmark API token -- templates aren't testable with Postmark's
sandbox token.)
Fixes#121
If you are using an SES ConfigurationSet with open or click tracking
enabled, SES replaces non-ASCII characters with question marks as it
rewrites the message to add tracking, if the bodies are sent with
`Content-Transfer-Encoding: 8bit` (which is Django's default for utf8
body parts).
Force potentially problematic parts to use CTE: quoted-printable
as a workaround.
Fixes#115.
This avoids problems with ESPs that don't distinguish *Content-ID*
from attachment filename, where a local hostname ending in ".com" could
cause Gmail to block messages sent with inline attachments.
(Mailgun, Mailjet, Mandrill and SparkPost have APIs affected by this.)
Fixes#112.
