dovecot - Mar 2013 - Exposing masteruser info to cllients via lmtp-proxy connections

Hello,

Please somebody suggest me how to remove the "*masteruser" appendix
from the dovecot director database while using masteruser authentication.

My situation is:
- all users get authenticated in LDAP on the dovecot-director frontend
- then they are forwarded to dovecot backend as username*masteruser ( this is a
way how to proxy users with encrypted passwords). To enable it a added an extra
field in LDAP-dovecot configuration: destuser=%u*masteruser

This works OK, but problems are:
- I have lmtp-proxy on the dovecot frontend and I have to use the same 
"%u*masteruser" field in lmtp passdb because the director thinks that
me at mail.com and me at mail.com*masteruser are different users and would send
lmtp-proxy connections to other dovecot backend.
Here is a problem: "Delivery-To" and "Received" fields in
any email contains "*masteruser" ! I need to remove any mentions about
"masteruser" authentication from client emails.

Also another little problem:
- If I run "doveadm status" tool then to get user's data I need to
specify user as "username*masteruser"

Thank you in advance.

Not sure about how to fix that, but maybe you can get rid of the *masteruser
completely? Instead of using that, just return "master=masteruser"
field.
