Below are the port numbers for both incoming and outgoing protocols. These include the port numbers that support as well as do not support encryption.

Another cause of this error is the operating system registry corruption. A registry is a library system used to store all important data about the operating systems such as configuration, subject, and program settings.

Each time we install a program on the computer, entries are made in the registry.  However, installing and uninstalling programs leaves many of these inputs behind resulting in a number of problems. These include poor system performance, programs that do not work, system instability and random errors.

Therefore we suggest our customers to use maintenance tools such as registry cleaners. This helps to repair the damage and acts as a viable preventative measure.
