Open Source Document Management System | OpenKM

I am testing OpenKM 4.1 with JBOSS 4.2.3.GA on Windows XP SP3. I configured it to send email through external SMTP server at a web hosting company. Email notification works as expected. However, if the mail contains non-English (Thai) characters, they are unreadable if user login via my company iNotes (Domino Web Access 7.0.2). The non-English characters are readable correctly in other email clients.

I have tested sending another email from my Gmail account that also configured encoding UTF-8 and observed what is the differences between UTF-8 from Gmail and UTF-8 that is sent from OpenKM JBOSS.

Mail Header if sent from JBOSS:
charset: UTF-8
Content-Type: text/plain
Content-Transfer-Encoding: 7bit

Mail Header if sent from Gmail:
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: base64

Thai language sent from Gmail is displayed perfectly in iNotes but unreadable if sent from JBOSS. I am suspecting that encoding only 7bit should be a real cause.

My question is that, is there anyway to configure JBOSS mail-service or internal OpenKM somehow to send email using 8bits encoding insteads of 7bit.

You'll might take a look on jboss forum, because it's something about jboss mail configuration

Thanks for your suggestion.

I was struggling with this for couple days without a way out. I have searched almost a hundred of JBOSS forum but still haven't seen the way to enforce 8bit encoding when it is sending email. All configuration examples have mostly demonstrated "UTF-8" settings already. But when email arrives, the header always be like ...

charset=UTF-8
Content-Transfer-Encoding: 7bit

I suggest you put a post in jboss forum, there're the people who knows much about jboss configuration.
