Hello List,

I'm using maildrop with postfix and openldap to store the users.

Occasionally maildrop bounces a message with: user unknown. Command output: Invalid user specified

This should not happen, if the user didn't exsist postfix would not have
accepted the message.

Could it be that the ldap lookup that maildrop does fails ?

Is it possible that maildrop returns a temporary error so mail will stay in the
postfix queue untill a next attempt ?

Any other suggestions that prevent this from happening ?

Thanks in advance
