[rt-users] E-Mail system check by round trip email

[Marco Dieckhoff]

Hi!

Is there any check for an E-mail system that sends an email via an 
(external) smtp server and looks if that email is received (in a set 
timeframe) on a pop3/imap account?

If not, how do you ensure that incoming mails reach your local server?


Infrastructure:
We have an external mail provider, putting all mail in a catchall account.
A tool called "popcon" fetches the mails from that account, checks for 
viruses and has a rudimentary spam detection, and then delivers via our 
local Exchange server to the original recipients mailboxes.

So we have multiple spofs.
I already surveil smtp, pop and imap on both the external and our 
Exchange server.

But that won't find popcon failures, or other delivery problems.
