LOGIN/PLAIN

    Hello, your hosting provider has discontinued an obsolete technology. As a consequence, SMTP does not work and does not send out mail.

    The hosting provider says:

    “Currently, the smtp.forpsi.com SMTP server is configured so that the CRAM-MD5 authentication method is still available, but only for specific domain names. Most SMTP email sending systems, including the WP Mail SMTP plugin, will choose from the available authentication methods offered by the SMTP server (currently LOGIN, PLAIN and CRAM-MD5). Within the next two to three months, the use of the CRAM-MD5 authentication method will be completely removed from our SMTP server and the server will no longer offer it. After that, your system will continue to work as it will only be able to choose between LOGIN or PLAIN authentication methods.”

    Now in this situation, what can be done to re-manage the form messages? and deliver it to the target? What settings should be made? Can the extension handle this new more modern technology?

    Thank u so much!

  • Hi @szilard21,

    Thanks for reaching out. `The “Other SMTP” mailer uses the PHPMailer.php class, which is bundled in core WP. Our plugin does not specify/set the Authentication so by default it should try all of the authentications. The comment of authentication type is:

    Options are CRAM-MD5, LOGIN, PLAIN, XOAUTH2, attempted in that order if not specified.

    So, you’ll likely don’t need to do anything as it uses the Authtype that the SMTP server offers.

    I hope this helps!

    Thank you for your reply!

    Then I don’t know what the problem is, why the mail didn’t go out. It only worked because the server company reset the old technology.

    Hi @szilard21,

    Thanks for getting back. In that case, you can specify a specific Auth type using a little custom code which I’ve included below:

    add_filter( 'wp_mail_smtp_custom_options', function( $phpmailer ) {
	$phpmailer->AuthType = 'LOGIN';
	return $phpmailer;
} );

    In case it helps, you can follow this documentation on easily adding custom code snippets.

    I hope this helps!
