What is alert 8144?


A POP3 client has logged on to GMS and unexpectedly issued a USER command. This command should never be issued at this stage so it is likely that

  • there is a problem with the remote POP3 client; or
  • someone is attempting to gain control of your server.

In this case, session Undefined was processing a connection from Undefined when the client sent the command Undefined. GMS responded with

-ERR Commands out of sequence

To resolve this problem, you will need to identify the user of the system at Undefined and find out what they are doing. Perhaps you should suggest that they use GMS Webmail to access their email. If there was an attempt to gain control of your system, GMS has identified it and stopped it.
