Recently built a test environment inside: 2008r2 system, MD12.0.1, client software foxmail 6.5. When sending and receiving mail through the client, the log error screenshot is as follows:
Simple analysis: The client's IP address is 10.10.21.112, the server is the LAN internal 10.10.20.10, the client account after the server's SMTP authentication, indicating that the sender should be no problem, under normal circumstances mail from command return sender OK. But here is the hint 553 this server does not accept routed mail, and then directly error Winsock error 10054 connection is reset by the other end! Less than a second from mail from to 10054, this should be related to antivirus software, firewalls, and data execution protection on mail services.
Antivirus software does not look, the newly installed system has not had time to install anti-virus software. To the firewall of the control panel look, sure enough the firewall is still open, shut down the firewall. The test will be successful. Oh, if it is not successful, please restart the server Oh!
Tip: Before installing the MDaemon mail server, please refer to the basic requirements of the system environment, the summary of their own, hehe. 1, the system itself has not installed SMTP service, if you please shut down the server, otherwise the MD installation can not start. 2, shut down Windows from the firewall (this needless to say the control Panel to look for), so as to avoid my problem oh. 3. Turn off Data Execution protection (computer---Properties---advanced---performance---settings---Data execution protection---choose to perform data protection only for critical Windows programs. 4, after the installation is completed, remember to mdaemon the directory from the antivirus software Oh. Another 2008 of UAC is pretty annoying ... Oh
