When I read those threads before, I though the problem was confined to usernames. Surely there should be some sort of documentation on this to prevent people wasting countless hours trying it. The wiki documentation recommends using . separator for Maildir++ because it's native imap.
I still think this is a bug. For some reason virtual handles it with no problem, but shared falls in a heap. To me it looks like %% and % are interpreted differently. depending on the namespace type. Surely, maildir:/var/mail/vhosts/%%d/%%n/mail:INDEX=/var/mail/vhosts/%d/%n/shared/%%u is no harder to translate than virtual:/var/mail/vhosts/%d/%n/virtual should I file a bug report? I'm not confident changing the separator to /. I have a lot of mails imported with the . separator and I'm worried something will get lost. - Hugh
