Docker: Mailhog "connection refused"

Question

I have a php-fpm container which should be sending mail to another container using Mailhog. The error message is:

 Swift_TransportException: Connection could not be established with host mailhog [Connection refused #111]

The container definition looks like this:

 mailhog:
   image: mailhog/mailhog:latest
   restart: unless-stopped
   ports: 
     - 1025:1025
     - 8025:8025
   networks:
     mine:
       aliases:
         -mailhog

The command to send mail is:

 /usr/bin/mhsendmail --smtp-addr mailhog:1025

... which superficially seems to me to be everything that (the Mailhog docs say ...) I should need to make this work. So, what exactly can cause connection refused?

Okay, I can see from other sources that this message means, "no process is listening or it's blocked by a firewall."

Are the containers on the same network ? Try to ping mailhog from your php container. — davidxxx, Mar 04 '20 at 16:15

False Alarm!

I determined that the php.ini settings for mail were incorrect. They specified the wrong port!
