Checking SMTP in OpenCart settings 3
The module adds a convenient button to the OpenCart 3 administrative panel for checking SMTP settings directly on the store settings page.
After installation, the administrator will be able to check the connection to the SMTP server, authorization and sending a test letter without having to save settings, wait for the actual order to be sent, or look for the cause of the error in the logs.
The module is especially useful when setting up store mail for the first time, changing the SMTP server, moving a site to another hosting, connecting corporate mail, setting up mail through Yandex, Mail.ru, Gmail, Beget, Timeweb, Reg.ru and other mail services.
A verification button is added to the store's mail settings tab. The administrator can enter the SMTP host, login, password, port,timeout and immediately check if the connection is working. If necessary, you can specify an email to send a test letter.
The main task of the module is to quickly understand whether sending mail via SMTP is configured correctly.
This will be especially useful when emails from the site are not received, orders are not sent to customers, administrator notifications do not work, or you need to check new SMTP data before saving the settings.
The module shows the test result in stages: connecting to the server, EHLO request, encryption, authorization and sending a test letter. This helps to quickly understand where exactly the error occurs: in the host, port, encryption type, login, password, or the sending of the letter itself.
If the email for the test letter is not specified, the module only checks the connection andauthorization.
If an email is specified, an additional test email is sent to the selected address.
