Re: [Dovecot] Best way from Mbox to Maildir using 2.17?
Thanks for the tips Noel I'll give that a go. I'm moving just a small number of mailboxes over from system users on one server to a new server using a virtual user setup = dovecot + postfix postfix admin using MySQL. Thanks!

Never noticed this, but, it was a very very long time ago I last used it, and since most users over here have always been pop3, probably never had many to convert in the first place when I did use it, so risk was so low. I think it was around the time we merged, and had to combine sendmail/dovecot and qmail/vpopmail/dovecot systems into just a postfix/dovecot solution, either we fluked it, or any affecteds didnt bother to report it.

As Charles has already mentioned, thats how Maildir works I'd modify this to 'the way Maildir wants it'not necessarily the way it _must_ work. I suspected the preference, but, again, didn't have enough time to investigate. (Some) users requested that their folders be visible, which is what they were familiar with under mbox. BASH to the rescue and a short while laterPOOF! Also, Thunderbird is quite happy creating folders without the preceding '.', which seems to work without incident with the Maildir format. ...and in case it's not quite obvious by this point, the intricacies of e-mail storage are not my long suite.
