Abstract: A disclosed example method to monitor an email system involves sending a first test email from a first email system to a second email system. The first test email is addressed to a first destination email address associated with the second email system and having first information identifying the first test email and the second email system. The example method also involves retrieving, from an email account having a second destination email address different from the first destination email address, a plurality of other test emails from other email systems being tested for operability. The other test emails include second information identifying corresponding ones of the other test emails and corresponding ones of the other email systems. The example method involves determining whether the first test email fails to arrive at the email account within a time period from the second email system.

Abstract: An example method to monitor an email system involves sending a test email to an email server. The email server is to automatically forward the test email to a plurality of email accounts of corresponding domains different from one another and different from the email system. When the test email does not arrive at the plurality of email accounts within a time period, a notification identifying the email server is generated. Other test emails are distinguished from the test email based on checksum values in subject fields of the test email and the other test emails. The other test emails correspond to different ones of a plurality of other email systems being tested for operability. Each checksum uniquely identifies a respective one of the test emails and a respective one of the email systems.

Abstract: An end to end email monitoring system which monitors and verifies the ability of a client mail system to send and receive email messages to and from local and remote networks. The monitor tests inbound email flow, internal email services, database availability, and outbound email flow. It uses checksums for precise identification and allows emails from multiple client environments to arrive in a single, shared Internet test account. The use of multiple targets for email verification eliminates false positives due to a single email destination being unavailable. Moreover, SNMP alerting is used in addition to email alerting to provide an out of band notification method. The SNMP alerting has been enhanced to send the identification of the tested email server as the source. The monitor stores historical information for 45 days and can produce detailed reports summarizing outage events and delay occurrences in addition to providing real-time alerts.
