A few months ago I went through this process and tried almost every email client out there. I came back to TB! for the following reasons (a) Other applications were slower /more bloated on my netbook (b) Other applications were usually missing features I'd become used to in TB!
The closest was Thunderbird, but it required so many add-ins to provide similar functionality that it slowed to a crawl. I'm hopeful that Thunderbird 3 (when announced) will address these issues. So I'm staying with 4.0.x until I see the next Thunderbird release (Jan/Feb '09) and then I'll decide. I'm only a POP3 man so I'm not worried about these IMAP discussions. Previous participants are right - that TB! has been promising improved IMAP for years, and they have re-written it more than once.. so I'm not sure what elese they can do. (I tried IMAP in Thunderbird - aand didn't see what the fuss was about... :) Graham ________________________________________________________ Current beta is 4.1.1.6 | 'Using TBBETA' information: http://www.silverstones.com/thebat/TBUDLInfo.html
