I've been sending logs and reports from 3 sites at the rate of 20 per site per day. It has always worked flawlessly - for years.
Suddenly, the emails don't get through from any of the 3 sites.
This happened for a few days about a year ago and then it fixed itself. So, I didn't get any insight from that.
Here is the path:
Device or program sends an email. addressed to an outside address
, via SMTP / local workstation LAN address where hmailserver is running (as a relay only).
hmailserver forwards the emails
to fred@r........k.com at our external ISP mail system.
The ISP mail systems forwards the mail to the addressee at a domain / mail server that I "own".
The domain mail server delivers the mail to a POP account on one of my external workstations.
email to firstname.lastname@example.org sent to server at [local IP addess]
hmailserver running at [local IP address] forwards mail via email@example.com.
ISP send mail to firstname.lastname@example.org
I get POP mailfor email@example.com in my office.
I have attached a log from the hmailserver which you my well be able to interpret better than I.
In order to fix the disruption, it would be good to know where it's faiing…..
