What do you dislike about Mailflow Monitoring?

The archive button for a mail monitor just archives the mail monitor, not the previous history, but it doesn't prompt or tell you this nor can you restore it. Minor problem. Devs are fixing it :-) Review collected by and hosted on G2.com.

"Cleanest approach to insure E-Mail service functionality, end-to-end."
5/5
What do you like best about Mailflow Monitoring?

Easy to configure, low cost ($0). Since it is an outside service, it is the cleanest approach to insure E-Mail Services, end-to-end. It takes a bit of skill to setup your local E-Mail server with the proper forwarding rules, but once done, you can configure the frequency of mail checks. The service sends a test E-Mail to your server, with specific identifying details. You then configure your forwarder to respond to this automated E-Mail with the properly configured response. This tests the following flow (for my use case):P MailFlow Monitor sends E-Mail DuoCircle mail filtering received the E-Mail Proper spam and virus checks are run DuoCircle forwards to my local E-Mail Server My local E-Mail server performs local spam/virus checks [Amavisd/clamd + Postfix + Dovecot + Sieve] postfix automatically responds to special E-Mail address outbound.mailhop.org receives response outbound.mailhop.org sends to original MailFlow Monitor -- IF HERE, WITHIN SMALL TIME-FRAME, SUCCESS -- Review collected by and hosted on G2.com.

What do you dislike about Mailflow Monitoring?

The service uses up some of my outbound.mailhop.org outgoing E-Mail quota. You pay for 150/day x N [N has a cost] Review collected by and hosted on G2.com.
