Re: [Dovecot] IMAP separator migration

Then you can have userdb set namespace/default/separator=/, namespace/others/separator=/ and namespace/pub/separator=/. Or a post-login script to set those in environment.

Thanks, this seems to work fine. In the interests of providing closure (for somebody trawling through mailing list archives with the same goal) I have:

namespace _private { type = private separator = . prefix = inbox = yes } namespace _shared { type = shared separator = . prefix = Users.%%n. location = maildir:/var/mail/virtual/users/%%n/Maildir/:INDEX=~/shared/%%u subscriptions = no list = children } namespace _public { type = public separator = . prefix = Shared. location = maildir:/var/mail/virtual/public:INDEX=~/public subscriptions = no }

and I've created a postlogin script looking like:

#!/bin/sh

case "$USER" in
iantest@example.com|mailtest@example.com)
                   ENV="NAMESPACE/_PRIVATE/SEPARATOR=/ 
NAMESPACE/_SHARED/SEPARATOR=/ NAMESPACE/_PUBLIC/SEPARATOR=/ 
NAMESPACE/_SHARED/PREFIX=Users/%n/ NAMESPACE/_PUBLIC/PREFIX=Shared/";;
                   export USERDB_KEYS="$USERDB_KEYS 
namespace/_private/separator namespace/_shared/separator 
namespace/_public/separator namespace/_shared/prefix 
namespace/_public/prefix"
          *)
                   ENV="";;
esac


exec env $ENV "$@"

The namespace prefix needs changing too. Note that the %%n seems to have been reduced to %n by the time of the postlogin script. The shell seems to dislike strange characters in environment variable names so I'm using env to set them.

Unmigrated '.' users work. Migrated '/' users work. Migrated users can see any user mailboxes. Unmigrated users can only see ones without period in them.
