We also have something local with a similar flaw. We're interested in an outside service that can send to outside addresses (including text messages) without depending on our email systems.

In short script creates and sends email that hops through all our mail servers, and checks email arrived in the mailbox. If it doesn't it triggers a Zabbix alert. The only flaw I have now is the Zabbix alert is an email that goes through the very servers I am testing. It's not perfect but it's a start. -ALF -Angelo Fazzina Operating Systems Programmer / Analyst University of Connecticut, UITS, SSG-Linux/ M&C 860-486-9075 From: [email protected]<mailto:[email protected]> [mailto:[email protected]] On Behalf Of Rosenbaum, Larry M. Sent: Tuesday, October 18, 2016 4:22 PM To: [email protected]<mailto:[email protected]> Subject: OT: SMTP round-trip monitoring We are interested in getting an outside service to do round-trip monitoring of our mail servers (i.e. check that SMTP mail is flowing in and out and send a notification if it isn't). [We are not interested in services that send an email to one of our mailboxes and checks it with POP or IMAP.] Can anybody recommend some commercial services I can check into? Thanks, Larry M.
