How to test port 110...


SLCheck can monitor your POP3 server by connecting to it periodically, e.g. once a minute. You can monitor Internet POP3 servers as well as POP3 servers in you local area network.

Command to monitor your POP3 server:

SLCheck -p 110 -a -r "+OK"

SLCheck tries to establish a connection to server The results are logged in file SLReport.csv. In dependence of the answer one of the following batch files will be executed:
  • CheckOK.cmd if the connection is successfull. That means that the POP3 server has answered with the right answer string "+OK" within 2000ms. That's the default timeout, you can change it with option -w. If you don't want a batch file to be executed if the attempt is successful you can add option -NoOkBatch.
  • CheckTimeout.cmd if the server doesn't answer within 2000ms.
  • CheckMismatch.cmd if the servers answers with a different answer string.

If you don't want any batch files to run (only logging) you can add option -NoBatch. Use -NoErrorBatch to suppress the execution of CheckTimeout.cmd and CheckMismatch.cmd.

To get the answer string of your POP3 server you can use the command without option -r:

SLCheck -p 110 -a

A window will occur showing the answer of the POP3 server.
