User-Agent: Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:1.7b) Gecko/20040311 Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:1.7b) Gecko/20040311 The To: field contains more than one whitespace after the first colon, in the specific case where a full name ("Jubal Kessler" <firstname.lastname@example.org>) is *not* included. This seems at first like a cosmetic issue, but turns out to have ramifications for Yahoo!'s DomainKeys anti-spam initiative, which basically creates a digital signature based on the entire message -- including the To: field. If Thunderbird creates a message with a To: containing more than one whitespace, then an MTA strips the leading whitespace, the digital signature becomes invalid. Reproducible: Always Steps to Reproduce: 1. Enable DomainKeys signing on the MTA. 2. Use this MTA as a client relay. 3. Send mail to email@example.com without using a full name. Actual Results: DomainKeys signature becomes invalid. Expected Results: Thunderbird should strip the leading whitespace, preventing DomainKeys from failing.
Reproduced with TB 0.7, Moz 1.8a3-0824, Win2K

This bug is still present in 2.0b1, nearly 3 years after initially reported! I found it the same way Jubal did, after some pain. I wonder how many Thunderbird users tried playing with DK and gave up in frustration because of this stupid little bug?
same on current trunk. within rfc822 spec, but still a privacy issue at the receiving end, no?
