This is the Number 1 useability issue with Thunderbird. 50% of my users want this functionality and cant find it. Why is thisnt a global setting -which 99% of people treat it as - with option to override on account settings page. --Patient X

Personally I think that's an excellent suggestion, but the forums would be place to discuss this, not least because the devs don't hang out here and thus won't catch wind of any suggestions/complaints made here. Someone in the forums might direct you to a relevant bug in bugzilla, too. --wintogreen 01:35, 9 November 2005 (PST)
