Perhaps. Or some sizing guidelines next to that setting in the config file so one can make some decision on how many mails you wish to support per folder... (Ie, 256MB -> max 471142 mails). Might be difficult to get an exakt number depending on CPU limits (alignment of data types in structs and stuff). Btw, why is the whole Dovecot system shutting down due to a bug in the 'imap' subprocess? It's rather annoying for the rest of the users... - Peter
