Example: From: =?ascii?Q?Some=2C_Guy?= <nobody@example.com> Or (real world example): From: =?iso-8859-1?Q?R=F6ll=2C_Sven?= <email@ddress.omitted> Reproducible: Always Steps to Reproduce: 1. send email for example via smtp: > From: =?ascii?Q?Some=2C_Guy?= <nobody@example.com> > To: user@example.com > Subject: test 2. read that email with mozilla Actual Results: The email-list view shows only the first part in front of the comma: "Some" or "Röll". The email's headers view shows only the part after the comma, "Guy" or "Sven". Expected Results: Both the headers and the list view should show "Some, Guy" or "Röll, Sven". http://www.faqs.org/rfcs/rfc2047.html says: IMPORTANT: 'encoded-word's are designed to be recognized as 'atom's by an RFC 822 parser. So I would not expect an address to be broken by any chacater which is rfc2047 encoded.
