> When you set an attachment filename before having a Content-type defined, then the Content-type is set to 'text/plain'.
> {code:language=java}
> BodyPart attachmentPart = new MimeBodyPart();
> attachmentPart.setDataHandler(dh);
> attachmentPart.setFileName("test.pdf");
> {code}
> ==> Content-type = 'text/plain'
> {code:language=java}
> BodyPart attachmentPart = new MimeBodyPart();
> attachmentPart.addHeader("Content-Type", "aplication/pdf");
> attachmentPart.setDataHandler(dh);
> attachmentPart.setFileName("test.pdf");
> {code}
> ==> Content-type = 'text/plain' (because setDataHandler reset Headers)
> {code:language=java}
> BodyPart attachmentPart = new MimeBodyPart();
> attachmentPart.setDataHandler(dh);
> attachmentPart.addHeader("Content-Type", "aplication/pdf");
> attachmentPart.setFileName("test.pdf");
> {code}
> ==> Right Content-Type
> {code:language=java}
> System.setProperty("mail.mime.setcontenttypefilename", Boolean.FALSE.toString());
> BodyPart attachmentPart = new MimeBodyPart();
> attachmentPart.setDataHandler(dh);
> attachmentPart.setFileName("test.pdf");
> {code}
> ==> Right Content-Type
> {code:language=java}
> BodyPart attachmentPart = new MimeBodyPart();
> attachmentPart.setFileName("test.pdf");
> attachmentPart.setDataHandler(dh);
> {code}
> ==> Right Content-Type
> It's because of solution of GERONIMO-2091 (SVN rev412720).
> The right solution is in [javamail MimeBodyPart.java|https://java.net/projects/javamail/sources/mercurial/content/mail/src/main/java/javax/mail/internet/MimeBodyPart.java?rev=569] : use direct access to Header (instead of method with default value) and do nothing if not yet defined. This solution could allow to remove the {{MIME_SETCONTENTTYPEFILENAME}} property.
