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
Python 3.3 moved various collections abstract base classes from
`collections` to `collections.abc`, but also kept them available in
`collections` for compatibility with Python 2. Python 3.8 will allow
importing only from `collections.abc`.
(`collections.abc` hasn't yet been added to six.moves; see
https://github.com/benjaminp/six/issues/155.)
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.
The python3.7-dev environment available on Travis default trusty is
apparently an outdated beta. Released Python 3.7 is only available in
Travis on the xenial platform (and xenial is currently only available
with sudo=true).
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.
Current Travis default Trusty image doesn't support latest Python 3.7.
(The outdated 3.7 alpha it has available is buggy, but is sufficient
for our tests until a Xenial image is ready.)

SendGrid does not always correctly provide the sent Message-ID header value
to a tracking webhook's smtp-id field, making it unreliable to use for Anymail's
`message_id`.
Instead, generate a UUID `message_id` for Anymail tracking, and pass it from
send to webhooks in SendGrid custom args as anymail_id.
Webhooks will fall back to smtp-id for compatibility with previously-sent
messages that didn't have an anymail_id custom arg.
Fixes#108
Discontinue support/testing for Python 3.3 with Django 1.8.
Closes#99
Focus Travis testing on currently-supported Django/Python combinations.
(But keep a few older ones in the matrix, too.)
Delay raising AnymailImproperlyInstalled from webhooks.amazon_ses
until an SES webhook view is instantiated. Allows anymail.urls
to import webhooks.amazon_ses without error.
Fixes#103
