            Bug ID: 4670
           Summary: To/CC incorrectly escaped with a trailing backslash
           Product: Claws Mail
           Version: 4.1.1
          Hardware: PC
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P3
         Component: SMTP
          Assignee: users at lists.claws-mail.org
          Reporter: kuba at kernel.org

Using the string "linux-arm-kernel at lists.infradead.org" followed by multiple
spaces as a name in the To/CC list leads to the closing quote being escaped:
"linux-arm-kernel at lists.infradead.org\"
Which in turn leads to invalid address rejected by mailing lists / servers etc.

It happens regardless of the mail address, so for instance:
To: "linux-arm-kernel at lists.infradead.org"                   
<your at address.com>
will also get mis-escaped (making this problem very easy to repro).

It does _not_ happen when there's only one space between closing " and <, so
this:
To: "linux-arm-kernel at lists.infradead.org" <your at address.com>
seems to work just fine.
