Content-Transfer-Encoding Ends With Space Bug

[ozkanogun]

Hello,

If in mail Content-Transfer-Encoding ends with a space character, EmailConverter.mimeMessageToEmailBuilder method throws an error. Is it fixable?

Example code :
MimeMessage message = EmailConverter.emlToMimeMessage(emailfile);

EmailPopulatingBuilder pop = EmailConverter.mimeMessageToEmailBuilder(message);

Example Email

Content-Type: multipart/alternative;
boundary="2cu1j27uX5Y7=_?:"

--2cu1j27uX5Y7=_?:
Content-Type: text/plain; charset="utf-8"
Content-Transfer-Encoding: 7bit

text plain
--2cu1j27uX5Y7=_?:
Content-Type: text/html; charset="utf-8"
Content-Transfer-Encoding: 7bit

text html
--2cu1j27uX5Y7=_?:--

Exception stack trace :

Do you have an EML file for me to download? The EML text you posted seems incomplete.

test.zip

Here it is, i added the test EML file, as i said the problem is at the "Content-Transfer-Encoding: 7bit " lines 7bit ends with a space character. If you trim it at EmailConverter.buildEmailFromMimeMessage or at ContentTransferEncoding.byEncoder the problem must be fixed.

Well, the message parsed just fine with the latest version. But then we did fix this in #546, I think.
