Hello,
I hope somebody out there can help me with my problem concerning postfix.
I discovered yesterday that the connection between our postfix server which is a relay host with an acl and our exchange server seems to be temporarily broken or is unavailable. There is the message in the logs: connection timed out (port 25)
It seems to me that the mails are being sent after a postfix restart.
Here are the common outputs/configs. If more is needed, just ask for it.
Regards

If I restart postfix then it seems to me that the mails are being sended:
