I am trying Thunderbird 1.0. I've tried Thunderbird several times in the past, but always found problems with its IMAP support. However, Thunderbird 1.0 seems much more responsive with IMAP, especially when checking large amounts of subfolders. I may actually be able to stop using OE. :)
Question: Does anyone know how to force the Send button in Thunderbird to default to Send Later?
