[RFC-5322 allows](https://tools.ietf.org/html/rfc5322#section-3.6.2)
multiple addresses in the From header.
Django's SMTP backend supports this, as a single comma-separated
string (*not* a list of strings like the recipient params):
from_email='one@example.com, two@example.com'
to=['one@example.com', 'two@example.com']
Both Mailgun and SparkPost support multiple From addresses
(and Postmark accepts them, though truncates to the first one
on their end). For compatibility with Django -- and because
Anymail attempts to support all ESP features -- Anymail now
allows multiple From addresses, too, for ESPs that support it.
Note: as a practical matter, deliverability with multiple
From addresses is pretty bad. (Google outright rejects them.)
This change also reworks Anymail's internal ParsedEmail object,
and approach to parsing addresses, for better consistency with
Django's SMTP backend and improved error messaging.
In particular, Django (and now Anymail) allows multiple email
addresses in a single recipient string:
to=['one@example.com', 'two@example.com, three@example.com']
len(to) == 2 # but there will be three recipients
Fixes#60
Fix incorrect change from Django 1.11 release.
Intent is to run live tests on newest released Django
under Python 3, and on oldest supported Django under
Python 2.7. (Though they should -- and do -- pass under
pypy. Just trying to conserve ESP testing credits.)
Issue a better error message if message.reply_to
is set to a single string.
(Would also like to do this for to, cc, and bcc,
but Django core EmailMessage.recipients is called
and stumbles over thoses cases before Anymail's
backend gets involved.)
Fixes#57
Track change to Mailgun's events API, which
no longer includes message recipients.
(Only affected check for successful send
in the integration tests; Anymail doesn't
use the events API outside test code.)
Fixes#58
* Mandrill now refers to "whitelist change" events
(used to be "whitelist sync").
* More details on solving validation failures due to
webhook url mismatches.
* The default (GitHub) readme should point
to the stable docs version, rather than
the latest development version.
* The frozen links in PyPI should use the full
patch version number (X.Y.Z), not just the minor
X.Y version. (Leftover from Djrill's branch-based
version management; Anymail uses tags
for versions, and old way was creating incorrect
frozen doc links for patch releases.)
Only real problem is in json serialization tests:
Python 3.6 [changed][1] the json serialization
error message to use the object's class name
rather than its repr. E.g.:
"Decimal('19.99') is not JSON serializable"
becomes:
"Object of type 'Decimal' is not JSON serializable"
Update tests that looked for specific serialization
error message to just look for the word "Decimal"
instead. (Works with all Python versions.)
[1]: https://bugs.python.org/issue26623
* **Future breaking change:**
Rename all Anymail backends to just `EmailBackend`,
matching Django's naming convention.
(E.g., switch to "anymail.backends.mailgun.EmailBackend"
rather than "anymail.backends.mailgun.MailgunBackend".)
The old names still work, but will issue a DeprecationWarning
and will be removed in some future release.
(Apologies for this change; the old naming convention was
a holdover from Djrill, and I wanted consistency with
other Django EmailBackends before hitting 1.0.)
Fixes#49.
Mandrill's webhook signature calculation uses the
*exact url* Mandrill is posting to. If HTTP basic
auth is also used, that auth is included in the url.
Anymail was using Django's request.build_absolute_uri,
which doesn't include HTTP basic auth. Anymail now
includes the auth in the calculation, if it was present
in the request.
This should eliminate the need to use the
ANYMAIL_MANDRILL_WEBHOOK_URL override,
if Django's SECURE_PROXY_SSL_HEADER and
USE_X_FORWARDED_HOST (and/or
USE_X_FORWARDED_PROTO) settings are correct
for your server.
(The calculated url is now also included in
the validation failure error message, to aid
debugging.)
Fixes#48
SendGrid: update to v3 send API
**SendGrid:** **[possibly-breaking]** Update SendGrid backend to newer Web API v3. This should be a transparent change for most projects. Exceptions: if you use SendGrid username/password auth, esp_extra with "x-smtpapi", or multiple Reply-To addresses, please review the [porting notes](http://anymail.readthedocs.io/en/latest/esps/sendgrid/#sendgrid-v3-upgrade).
Closes#28
In BasePayload, ensure any Django ugettext_lazy
(or similar) are converted to real strings before
handing off to ESP code. This resolves problems where
calling code expects it can use lazy strings "anywhere",
but non-Django code (requests, ESP packages) don't
always handle them correctly.
* Add utils helpers for lazy objects (is_lazy, force_non_lazy*)
* Add lazy object handling to utils.Attachment
* Add lazy object handling converters to BasePayload attr
processing where appropriate. (This ends up varying by
the expected attribute type.)
Fixes#34.
Anymail was requiring Mandrill's webhook authentication key for the initial webhook url validation request from Mandrill, but Mandrill doesn't issue the key until that validation request succeeds.
* Defer complaining about missing Mandrill webhook key until actual event post.
* Document the double-deploy process required to set up Mandrill webhooks.
Fixes#46.
Add support for Postmark's recently-released [delivery tracking webhook] to Anymail's normailized status event handling. The existing Anymail tracking webhook URL can be copied to "Delivery webhook" in your Postmark outbound server settings.
Closes#45.
A message's `from_email` and each address in its `to`, `cc`, and `bcc` lists must contain exactly one email address. Previous code would silently ignore additional addresses, leading to unusual behavior. Now, raises new `AnymailInvalidAddress` exception.
Example: `from_email='Widgets, Inc. <widgets@example.com>'` is invalid: it needs double-quotes around the "Widgets, Inc." display-name portion. In earlier versions, this probably would have sent the message from something like "From: Widgets <@localhost>". Now, it will raise an exception.
**Potentially-breaking change:** If your code is using an unquoted display-name containing a comma in an email address, it will now raise an error. In earlier versions, this may have appeared to succeed, but was almost certainly not doing what you intended.
Fixes#44.
* Trailing comma after "anymail" (see #40)
* Note order doesn't matter
* Change tuple to list (match examples to
Django 1.9+ project template)
[ci skip]
Compatibility with Python 2.7 versions older than 2.7.7
* Use Django's constant_time_compare method
* Include sparkpost in test requirements
* Don't use non-public `EnvironmentVarGuard` in tests
Fixes#41
Allows clients that use AnymailMessage or AnymailMessageMixin
to access (e.g.) message.anymail_status.message_id without
an AttributeError, even when using a non-Anymail backend
(e.g., during testing).
Also clarify docs of anymail_status attribute to note it only gets
attached to a normal Django EmailMessage when sent through
an Anymail backend.
(May help with situation described in #36)
Drop `from __future__ import unicode_literals`;
it was there for Python 3.2 compatibility (which
Anymail doesn't support). Ensures tests use normal
strs in Python 2.x.
