What is alert 8202?
A remote POP3 client has attempted to connect to GMS but there are already too many POP3 sessions. Therefore this request to connect has been rejected. By default, GMS will allow upto twenty simultaneous connections. There are several reasons why all sessions may be in use:
- Too many clients are connected to the server;
- Clients are connected longer than usual because there are a large number of users downloading email over slow Internet connections;
- Someone is trying to connect to your system malicously in order to use all your resources and prevent legitimate users access.
In this particular case the connection from the IP address Undefined was rejected by GMS with
-ERR Busy please try later
If you wish to allow more simultaneous connections, you can increase the number of connections in GMS session control.
