Thread Safety

Public static (Shared in Visual Basic) members of this type are safe for multithreaded operations. Instance members are not guaranteed to be thread-safe.

Remarks

This exception is usually thrown on attempt to connect to a wrong port (for instance, if the client attempts to initiate TLS/SSL secure POP3 connection on port 110 instead of dedicated TLS/SSL port 995).

If the dedicated TLS/SSL port is closed on the mail server, the client should attempt to connect using regular port (such as 110 for POP3) and then switch into TLS/SSL mode via STARTTLS (either using StartTls method of the mail component or specifying UseStartTls as SslMode property value).

Another reason of having this exception thrown is an attempt to establish SSL connection using a client certificate when wrong password for this certificate was specified.

The developer can obtain Win32 code of the occurred error from NativeErrorCode property.
