Why has the SMTP or POP3 service failed?

0

This can happen when you installed another application that relates to resources needed by the mail server and has created a device or port conflict. To be more specific: 1. In the case where you have installed a Anti-Virus software for email protection, then port 110 [ POP ] and or port 25 [ SMTP ] conflicts may occur. . To correct this, change the port for the Anti-Virus software monitors. If your Anti-Virus software does not allow you to change the port, then you must disable the Anti-Virus software in order to use Winmail. 2. In the case where you have installed proxy server software, then port 110 [ POP ] and or port 25 [ SMTP ] conflicts may occur. This is because some proxy servers simultaneously have a mail proxy function. You will need to stop the mail proxy function of those proxy servers. 3. Port conflicts may also occur in the case where there is a firewall application installed. You will need to open the following ports: 25 [ SMTP ], 110 [ POP3 ], 6000 [ Admin ], and 6080
