Previously, the SendTransactionalEmail API method was not rejecting domains that have been unsubscribed in an account and system-wide unsubscribed domains. For example, the domain antihotmail.com is a domain that is in the JangoMail system-wide blocklist.
This has now been corrected.
Now if you use SendTransactionalEmail to send to email@example.com, the following exception will be thrown:
JangoMailNamespace.SystemDomainAddressException: Web Service Exception SystemDomainAddressException: Email address is on system-wide domain block list.
Similarly, if you unsubscribe the domain abccompany.com within your individual JangoMail account, and then you attempt to send an email to firstname.lastname@example.org via SendTransactionalEmail, this exception will be thrown:
JangoMailNamespace.UserDomainAddressException: Web Service Exception UserDomainAddressException: Email address is on account's domain block list.
