Alert emails not being sent

@mysticalunicorn wrote:

I have haproxy setup locally and I am using a SMTP server to send email alerts which works fine. I setup the mailers section and then add the config to the backend which sends alerts when any of the 3 backend servers are down.

I moved the configuration to our aws vm and it does not work. I take a backend server down and no alerts are sent. checked the stats page and the health check fails which means haproxy sees it as down and an alert should be sent. I manually connected to the smtp server with telnet and sent an email and it works fine, this means port 25 is open and the vm CAN connect to the SMTP server.

I then installed tcpdump and monitored port 25 then took one of the backend servers down. NO data on port 25 which i think means haproxy is not even trying to connect. any ideas ?
Im using haproxy 1.8
thanks for any help.
