Simplomon reports the following exception when it attempts to connect to my Postfix mail server:

Got an exception during check: Unexpected response from SMTP server: '503 5.5.1 Error: send HELO/EHLO first

I am willing to provide credentials to a test account if needed for troubleshooting.

thanks for this - investigating, and I wonder what is going on since I had to change the order to be like this to get it to work with my postfix.

hi Derkades, I can't reproduce this - simplomon sends out an EHLO as the first thing it does. Can you check using latest version of simplomon?

Thanks for taking a look. I am using the docker image, could you push an updated image to docker hub?
