[4.x]: Craft not sending STMP emails.

[zzseba78]

What happened?

Description

Craft 4 doesn´t send emails using STMP protocol. Doesn´t send test emails from Admin section ( test email ) and doesnt send email using Contact Form plugin. The email is from the current hosting and domain. Triple check username, server, port and password. From the Craft Admin test ( Email ) the test email show as sended ( attach screenshot )

Uploaded a PHPMailer test file using same email account with SMTP and works great, on the server and in localhost.

Update

Tested with a clean ( no plugins at all ) latest Craft v4 install, and doesn´t work either. Use several SMPT mails accounts that i know are working.

Log file in /storage/ folder shows this ( cleared all the file, just show this on contact form send ).

I just tested Settings->Email using SMTP settings on a fresh Craft 4.5.2 install and I received the test email successfully.

It did turn up a UI bug, but I don't think that it is related.

Focussing on the Settings->Email test only, can you load that page in the control panel, enable DevMode, delete the contents of Craft's storage/logs folder, then click the "Test" button, and share a zipped storage/logs folder? Feel free to send to [email protected] and reference issue 13611 if you don't to share publicly.

@angrybrad Yes, i spotted the same ui bug, but when i try to save it throws the error and fill the fields.

and share a zipped storage/logs folder?

Sure, i just sended it. Thank you.

Craft 4.5.3 is out now with a fix for that UI bug.

For posterity, it looks like the OP’s underlying issue was a blocklisted email server.
