Description
Expected behavior
Receiving e-mail from tätu [example.com] <sender@example.com> and expecting the sender name and e-mail address being displayed. In addition I expect to be able to respond to that e-mail.
The From header is formed as: From: =?UTF-8?Q?t=c3=a4tu_[example.com]?= <sender@example.com>
Actual behavior
The sender is shown as null. Responding to such e-mail is not possible. The e-mail is kept in the local Drafts folder. The user does not know about this until he opens the Drafts folder.
Steps to reproduce
- Compose an e-mail having an utf-8 sequence in the From header containing square brackets.
- Send it to an account having k9 installed
- Fetch the e-mail with k9
Environment
K-9 Mail version:
5.403
Android version:
8.1.0
Account type (IMAP, POP3, WebDAV/Exchange):
IMAP

No source file or test is named in the report. Reproduce the message using the provided From header and trace the sender parsing and reply flow; done means the sender name and address are displayed and replying no longer leaves the message in Drafts.
