At my company we have an E-mail server of Windows Server 2003 SP2 with Exchange 2003 SP2. Lately almost every month the receiving part of the mail isnt working. In the eventviewer we dont see anything which can relate that anything goes wrong with exchange and the mail. After a reboot of the server the mail comes in again and stays working good. Almost a month later the same problem comes up again and with the reboot we can force that the mail works again.
Since we arent able to find a cause for this problem we are hoping that anybody here can point us to the right direction for solving this.
Thanks already for helping.
