Add support for non-English attachment names

[ensean]

I meet a problem that while using this tool to send attachments with non-English name, it seems that the receiver's mail server can not decode the attachment name correctly. Detailed info is as follows:

Please note that the base64 data of the attachments are omit

• eml generated by this tool

So, is it possible the set the encoding method for the attachment name ?

I find a work around as follows...

mail.addAttachment(MimeUtility.encodeText(attachmentName), new FileDataSource(attachmentPath))

I've seen your issue and I still intend to fix it on my side as well...
