Dear All,
I am using perdition + courier + postfix+ ldap+ maildir (mail quota) on my mail servers.
All the functions are working fine on the server except one small issue.
I configured mail quota on the mail servers, suppose if the user quota becomes full
condition 1
if the sender mailbox and receiver mailbox existing on the same mail server the sender get a bounce back message that user quota is full.
if the sender and receiver mailbox existing on  two different machines , it doesn't  bounce back any messages.bcoz the receiver home directory is not existing on the same server

ERROR LOG
 relay=maildrop, delay=0, status=deferred (temporary failure. Command output: /usr/local/bin/maildrop: Unable to change to home directory.

I am looking for a breakthrough to tackle this issue

Any ideas and suggestions are welcome


Best regards
Paul
