Reproducible: Always Steps to Reproduce: 1. Enter a name with foreign or other non-standard characters in the "Name" for the identity of an account (POP3/IMAP etc). 2. Create a new mail 3. Send it - and the receiver will also see the ", instead of only the name. Actual Results: From: =?ISO-8859-1?Q?=22Nikolaj_J=F8rgensen_=28Stingbat=29=22?= <stingbat@stingbat.dk> - or, as UTF-8 encoded - From: =?UTF-8?B?Ik5pa29sYWogSsO4cmdlbnNlbiAoU3RpbmdiYXQpIg==?= <stingbat@stingbat.dk> Expected Results: From: =?ISO-8859-1?Q?Nikolaj_J=F8rgensen_=28Stingbat=29?= <stingbat@stingbat.dk> Simply NOT adding the quotes, if encoding is necessary. However, quotes should of course be added, when encoding is NOT necessary. This issue does NOT happen for the receiver (To:), this part works perfectly (that is, encoded correctly and without quotes). So only "Sender"-part is related.

Tried adding an identity with non-ascii chars, To and From look the same, and no encoded quotes - tested on Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.9b3pre) Gecko/2008020103 Lightning/0.6a1 Thunderbird/3.0a1pre ID:2008020103

Just did some more investigation. Actually it seems not to be related to the non-ascii characters, but rather if adding a ( or ) (perhaps also others) - which then makes the quotes get added. But weither or not it should be added, I'm not fully sure - but if it gets encoded, it probably don't "need" the quotes, or? Of course it depends on the RFC's, but... Some other clients just "sees" these quotes, which looks a bit odd. Thunderbird however, trims sender/receiver-name out, before "displaying". Minor problem of course, but would be nice if it looked alike on all clients (so weither or not it is a Thunderbird problem or if it's rather the other mail-clients which has the actual problem with not "removing" the quotes).
