Issue

An error occurs when sending email via SMTP with TLS enabled.

Steps to reproduce

1. Set up the SMTP configuration as follows: * Transport: SMTP * Host: url.to.smtp.host * Port: 587 * SSL: TLS

Adobe's page lists 2.4.8 - 2.4.8-p1 as compatible; the versions below are resolved from the current QPT constraints and are the ones the tool will offer.

Adobe scheduled the permanent fix for 2.4.9.

Install

Install the Quality Patches Tool with composer require magento/quality-patches, apply the prerequisites listed for all files applicable to your distribution and version first, then run vendor/bin/magento-patches apply AC-14985. On Cloud, add AC-14985 under stage.build.QUALITY_PATCHES in .magento.env.yaml.

For cweagans/composer-patches, choose a compatible version below and download the bundle. Copy its AC-14985/ folder into patches/composer/, merge composer.patches.json into composer.json, then run composer install. Bundle prerequisites the same way and list them first. Paths are relative to each package root, using the default -p1 level. Prefer local files when configuring composer-patches; a remote URL can change.
