Hey @PascalSchumacher! Thanks for the question - please feel free to ask questions on issues, it helps me know that people are still using JMail!
As for this specific question, it's a good one. I'll need some time to look into it as it's been a while since I've looked through the RFCs. I know that non-whitespace controls are allowed in quotes, but I'm not 100% sure on if they are allowed unquoted. I'm out of town for a couple of weeks but I will let you know once I get a chance to look further!
Hi @PascalSchumacher thanks again for this issue, it is a great catch. After reading through the relevant RFCs it does indeed look like control characters are not allowed unquoted. I will work on the fix for this asap.
Thank you very much! 😄 Looking forward to a release with a fix for this.
v1.6.3 is published with the fix! Thanks for your patience!
Is this bug report about an incorrectly validated email address?
If yes, what is the email address?
firstname_lastname\u0011@server.org
I maybe wrong but I think that RFC 822 disallows control characters in email addresses. Do newer RFCs allow them?
Sorry for using an issue for a question and thank you very much for providing JMail!
