What is a "_u.grp" file ?

Whilst looking into an issue I noticed users with the mail files ending "_u.grp" rather than the usual <date>.grp format. Does anyone know in what scenario are "_u.grp" files created?

Hey, Nathan. That indicates that the GRP was saved in UTF8, not unicode, so SmarterMail knows how to read the bytes. Standard GRP files are encoded in whatever format is set on the server.
