Sync On Arrival is a Thunderbird extension that instantly downloads new message headers as soon as fresh items are detected on the server.
The extension offers an additional benefit for users who have a Saved Search configured to show all unread email. This feature proves quite handy as it keeps the folders up-to-date, even if "search online" is not checked. The extension is compatible with Thunderbird version 1.0-1.5.0.*
The recent release has fixed several incompatibilities with other extensions, which was initially affected by Mozilla bug 174320. Additionally, a new feature has been added that enables users to troubleshoot some IMAP servers that only download the first message body when moving or copying several messages. This feature was requested by Ketil Lund, who helped develop the updated release.
Lastly, the updated release includes a new "Report a Bug" wizard that is available from the "Options" dialog. It is designed to encourage users to write bug reports when something's not working correctly and help report this information in a convenient way that is useful to the development team.
