How to integrate with MailHog in order to check emails?

[MagePsycho]

My warden environment is working fine. I can access installed Magento and MailHog (https://mailhog.warden.test/)
But when I place an order or register as a customer, I don't see any emails in MailHog.

Is there any configuration for MailHog with Warden?

[werfu]

If you look at MailHog documentation, https://github.com/mailhog/MailHog, you can see the SMTP service is listening by default on 1025. The port is also exposed through docker. So your container should be able to connect to the SMTP server to send email using mailhog:1025

[MagePsycho]

Does that mean, we need to install some SMTP extension and configure host=mailhog and port=1025?

[werfu]

Inside a warden shell, if you run a php -i | grep sendmail, you should see the default email configuration. mhsendmail, the mailhog sendmail replacement should be installed inside your container and pointing to your local mailhog instance. It should work out of the box.

Try running this:

<?php
$message = "This is a test!!";
$headers = "From: from@test";

mail("target@provider,test", "Testing", $message, $headers);

[navarr]

Following up on Maxime's message, the automatic configuration of PHP's sendmail should result in the mail command calls ending up in Mailhog.

Assuming that works, but Magento doesn't - there are a few different things that you should look for:

• Ensure you don't have an SMTP module or other type of mail module or capture module installed
• Ensure that you don't have email queuing turned on (or, run bin/magento cron:run manually a few times)

@werfu @navarr grepping sendmail gives

sendmail_from => no value => no value
sendmail_path => /usr/local/bin/mhsendmail --smtp-addr='mailhog:1025' => /usr/local/bin/mhsendmail --smtp-addr='mailhog:1025'
Path to sendmail => /usr/local/bin/mhsendmail --smtp-addr='mailhog:1025'

But when I try to send via a custom script (script.php)

<?php
$message = "This is a test!!";
$headers = "From: from@test";
try {

	mail("[email protected]", "Testing", $message, $headers);
	echo 'Success';
} catch (Exception $e) {
	echo 'Exception:' . $e->getMessage();
}

And running php -f script.php results in

error sending mail
2022/11/15 13:50:19 dial tcp 184.168.221.27:1025: getsockopt: connection timed out

@MagePsycho I've just tried your script on my env and it worked as expected.

sendmail_from => no value => no value
sendmail_path => /usr/local/bin/mhsendmail --smtp-addr='mailhog:1025' => /usr/local/bin/mhsendmail --smtp-addr='mailhog:1025'
Path to sendmail => /usr/local/bin/mhsendmail --smtp-addr='mailhog:1025'

@MagePsycho if you run a docker ps command, do you see a mailhog container running?

Based on the reference to 184.168.221.27 the issue here is mailhog is being resolved to mailhog.net likely as a result of a search domain being present in resolvconf More on this here: #415 (comment)

@MagePsycho / @werfu @navarr were you guys ever able to get mailhog emails to work?

[bap14]

@christian-walker Out of the box, it should "just work". There are some prerequisites though:

1. You've started the warden service (e.g. warden svc up)
2. You're using a Warden environment (magento2, wordpress, etc.)
3. You're script is being executed from a running warden project

Are you running an actual Warden project, or are you trying to use just the Warden docker image itself in your own docker-compose.yml file?

[christian-walker]

@bap14 thanks! My issue was with a 3rd party module disallowing emails to go through in general.
