autocreate ONLY for new Users

[plataleas]

Hi All

We are currently migrating accounts to Dovecot. The existing accounts do
have special folders with different names. (i.e. sent, sent-mail)

The autocreate-function of "special folders" is useful. However we need
this feature ONLY for new users. The existing accounts have a mapping
for their own "special folders".

There are discussions about this topic on the mailing list:

Did someone manage to implement this ? Are there workarounds?

Thanks and regards
