The Dovecot wiki mentions a plugin that will do a conversion when a user logs in. http://wiki.dovecot.org/Plugins/Convert That looks like it might be the handiest way but I haven't tried it and don't know how well it meshes with concurrent deliveries already being done in the new format. http://wiki.dovecot.org/Migration/MailFormat has other conversion tools. -- Les Mikesell lesmikesell at gmail.com
