User-Agent: Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; .NET CLR 1.1.4322) Build Identifier: I have an RFC 2047 encoded personal name in the To: line of an email. The personal name, when decoded, contains commas. The commas are incorrectly interpreted as mail address separaters, and thus the To: line in the message pane has three clickable links for the three different, comma delimited sections.

What program created that mail? I think the name is correctly decoded (aside from the missing "" arount Semi Genius). Without "" around the whole name it's normal to get this. I also tested KMail and got the same result. Additionally, the <mike@pgpqafullsail.com> in the line after the To: should start with a space or tab.

This mail was created from a custom JavaMail client.

Any mail client you know of that decodes/displays the To like you expect it?

Unfortunately, no. I would expect that the To: line would come out with one clickable address that contained "Michael Allen, \"Semi Genius\", <three Japanese characters>" as the single display name. Thunderbird can be the first to do this right! :-)

Well, how should the Client (e.g. TB) know that it's one name? Embracing such names with "" don't exist without reason. Why not teach the sending client to encode the field with the double quote? Not to speak from the missing whitespace before the email address (if it's no mistake created by submitting the header to bugzilla).

Christian is correct. The header provided defines multiple addresses, per RFC822. It is necessary to quote the name string in its entirety if commas are desired. Note that if the name string is going to be encoded (as this one is), the quotes must be included in the encoded portion (per RFC2047, section 5 item 3).

Well, I was mistaken. The arguments for parsing per the desired behavior are well set out in the duplicate. My apologies. *** This bug has been marked as a duplicate of 254519 ***
