Email Server Check Basics

This article will cover the setup and purpose of email server check functionality built into Uptime.com which includes three different checks. The following information provides examples and setup instructions for SMTP/POP/IMAP checks.

Adding Your First SMTP/POP/IMAP Server Check 

Simple Mail Transfer Protocol (SMTP), Post Office Protocol (POP) or Internet Message Access Protocol (IMAP) checks can be added by clicking Monitoring>Checks and selecting either SMTP, POP or IMAP from the Check Type list of drop-down menu options.

Monitor domain email activity on a continual basis with these checks.

Uptime.com requires the following details:

  • The check name
  • Check interval time (We are using a 5-minute interval for our examples)
  • Domain or IP to check (The only “Required” value)
  • Optionally, a string of text the check should expect to see

Please take a moment to familiarize yourself with the Field Explanation Support article.

Finalizing Your Check

Before saving your check be sure that you have included all of the required information for the following parameters.

  • Name of Check
  • Check Interval
  • Contacts
  • Locations
  • Check Type
  • Domain or IP

To locate check reports, click Reports>Alerts or view your most recent alerts from the Dashboard.

Other Commands

Each of these checks contains an Optional tab, which allows for users to enter a specific port or IP address to monitor, and define the encryption protocol preferred for Uptime.com to use.

Uptime.com fills in the IP address automatically, so users can adjust this value only as needed. This example shows the optional tab for an IMAP check. Note that the SMTP check is the only check in this grouping that allows for a username and password.

In addition to the Basic checks, additional checks can also be added to improve the process of monitoring your SMTP/POP/IMAP servers in multiple locations. Data captured can also be used throughout your company as Key Performance Indicators (KPIs) related to your SMTP/POP/IMAP servers.

While most of our fields are explained in Uptime Checks Field Explanation Support Article, we’ve also included a notes section in this check for any additional information you’d like to save with the check for future reference.
