POP3 Monitor

This SAM component monitor tests the ability of a POP3 server to accept incoming connections and respond with the correct code. It uses the following ports to poll Microsoft Exchange mail servers:

  • 102 X.400 MTA
  • 110 POP3
  • 119 NNTP
  • 143 IMAP4
  • 389 LDAP
  • 563 POP3 over SSL.
  • 636 LDAP over SSL.
  • 993 IMAP4 over SSL.
  • 995 POP3 over SSL.


This component monitor does not compute a statistic.

Field descriptions


A default description of the monitor. To override the default description, add to or replace existing text. Changes are automatically saved. The variable to access this field is ${UserDescription}.

Customize descriptions to specify what will be monitored so related alerts and notifications are more meaningful later.

Enable Component

Determines whether the component is enabled. Disabling the component leaves it in the application in a deactivated state not influencing either SolarWinds SAM application availability or status.

Port Number

This field is the port number used for POP3 connections. The default value is 110.

For Secure POP3 (SSL-POP), use port 995.

Response Time Threshold

Set the warning or critical threshold conditions based on the response time. The response time is the time in milliseconds it takes SAM to determine that a component is not Down and to retrieve any statistical data. See Application Monitor Thresholds.

User Notes

Add notes for easy reference. You can access this field by using the variable, ${UserNotes}.
