Hi! I am using ISPConfig 18.104.22.168. When I create mailbox on my server (for example "[email protected]") and try to send e-mail there from other mailbox, I will not receive it. When I look at "Mail-Queue" I have mail there with error: (temporary failure. Command output: ERR: authdaemon: s_connect() failed: Permission denied /usr/bin/maildrop: Unable to open mailbox.) Can some1 help me please?
