Hello,

I have installed irm 0.9.7 on my local ubuntu 16.04. I have user AD and LDAP for storing mail accounts. Web server is Apache. I logged successfully with AD account user1@armpddk,ba and when I sent mail to user2@armpddk.ba roundcube sad that messagge was sent successfully but in inbox of user2 there is nothing and when i opet user2 folder in vmail/vmail1/armpddk.ba/user2/Maildir all three folder new, tmp and cur are empty. I'm seding mail from my local ubuntu where irm is installed from webmail.armpddk.ba/mail.
I have followed official irm docs on installation and ldap AD intergration. Here is postfix log file when i log in and try to send a message
