We've deployed three bug fixes to JangoMail's SMTP Server, relay.jangosmtp.net. These three bugs were detected by customers relaying emails with eccentric attributes through the SMTP server.
1. Emails containing MIME boundaries with parentheses will now be properly handled.
Previously, emails with parentheses in the MIME boundaries, such as a boundary like:
Content-Type: multipart/mixed; boundary="nqp=nb64=()BDXjw0yWx"
would cause the JangoSMTP parser to throw an error. This is now fixed.
2. Emails containing unrecognized Content-Transfer-Encoding types will now default to "7bit".
Previously, if an email message contained an unrecognized or misspelled encoding type, like:
Content-Transfer-Encoding: 7 bit
would cause the JangoSMTP parser to throw an error. This is now fixed.
3. Emails containing foreign characters encoded as ISO-8859-1 will be properly handled.
Previously, an email containing certain foreign characters would have those characters replaced with ? marks or garbled when passed through the relay. For example, a Subject like:
Subject: Confirmation d'Inscription à la Liste de Diffusion - Liste TEST ML
would not have its foreign characters preserved. This is now fixed.
