Version: (using KDE KDE 3.5.6) Installed from: Gentoo Packages When I receive a message with a header line of the following form, From: =?iso-8859-1?Q?Lastname=2C_Firstname?= <some@example.com> this is parsed as: From: Lastname, Firstname <some@example.com> at the top of the message. Both "Lastname" and "Firstname <some@example.com>" are clickable as if the message came from two senders. When replying, the message is tried to be send to some@example.com AND to lastname@localhost.
according to RFC2822 Section 3.4 this is the correct behavior. As a workaround you can place the name in quotes when you reply From: "Lastname, Firstname" <some at example.com>
aehm, sorry. In the reply-msg it should be: TO: "Lastname, Firstname" <some at example.com>
Indeed, I just saw that a list of several senders is allowed for the From: header. I thought this wasn't possible. Then, of course, I'm closing the bug ... and I am annoyed at those bad clients people use to contact me :-)
