Lastname (no email) 2. Firstname <email@example.net> I am not able to reproduce by sending myself a mail from Shredder or from Gmail, as they both put double quotes around the sender name, such as "Lastname, Firstname" <email@example.net> It seems that this affects mails sent through a MS Exchange server, as they are encoded in latin-1 and not wrapped in double quotes Here is the (modified) relevent From: line in the actual message From: =?iso-8859-1?Q?Lastname=2C_Namewithaccent=E9e?= <last.first@example.net> Reproducible: Couldn't Reproduce Steps to Reproduce: 1.Receive a mail from a MS Exchange server? 2. ??? 3. Display It Actual Results: the message is displayed as coming from two different people: 1. Lastname (no email) 2. Firstname <email@example.net> Expected Results: the message should be displayed as coming from 1. Lastname, Firstname <email@example.net> This has an annoying side effect as when you reply to the mail, it sets both senders as To: but obviously one has no email, so it causes an error. It is very annoying, as you need to go back to the mail, edit it and send it again, everytime. I can provide any additionnal info from the original mail, but did not take the time to correctly anonymise it yet.
