SMTP Setup Failed

alexander-ushakov-93

Hello,

I am trying to setup custom SMTP server.

TLS, 465

But test sent mail failed with an error.

Please, suggest - where SMTP settings are stored in php file or in DB?

What log file I can check to figure out the problem root?

alexander-ushakov-93 settings for mail are configured in the admin. Check the logs under storage/logs if something fails. Most sending issues are caused by blocked ports on new servers or incorrect credentials.

It is generally not recommended to set up your own server for emails. I recommend using Mailgun as they have a generous free option of 3k emails a month. Setup via API is straightforward and easy as well.

@KBExit Sorry, but it is a requirement, and by definition is a simple task.

I think the problem is in hosting environment.

I had a problem where smtp doesn't work on php 8.2, but works with php 8.1. I had to stay in 8.1.

ikkeT that can't have been the issue. When switching php versions make sure to update dependencies with composer update. If that still fails check the logs. Php 8.2 is fully compatible.

luceos I agree. My site is on PHP 8.2 and it's stable.

I will retry one of these days and report back.

@luceos I promised to try and come back. I set up a test site today using the very same container setup I have with php 8.1. I changed the base container to be rhel 10 php 8.3. Same error results as earlier with 8.2 version.

I did all the mail configs and the basic configs while starting with 8.1 image. I verified the mail works. Then I built the very same flarum setup with rhel10 php 8.3, and restarted the container after chaning the updated base image. The installation and settings remained the same.

The email gets sent, but the "send test email" button causes red text: Oops! Something went wrong. Please reload the page and try again.

I enabled debugging, and the while I click the error text's debug link, I get:

ikkeT you need to disable deprecation warnings and you should run composer update between every php version change.

luceos excellent, thanks! This silenced the error message.
