Giuseppe Amato, is this bug still an issue for you? Have you upgraded to 1.3 Final, 1.3.1 or 1.4? If this bug *is* still an issue, please attach to this bug a sample email with the To: header as described. (Save the email to a .EML file, then use the Create a New Attachment link in the bug form.)

Bug still in 1.4 final official release: Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:1.4) Gecko/20030624 Following a sample e-mail, that contains this string in the To and From fields: =?iso-8859-1?Q?Marc_Andre=2C_Andr=E9-Netline?= <paipai@paipai.net>

That shows the problem. If the To: header has that text, it shows "To:" with the three names; if the From: header has that text, the reply is auto-filled with three names.
