  • Is StartTLS SMTP command supported in WP Mail SMTP? Full TLS transport is not always an option, unfortunately.

  • Hi @janr,

    STARTTLS is something that should be supported by your mail server which is used to create a secure connection using TLS or SSL. If you’re getting any errors, please share a full error log recorded when you send a test email from WP Mail SMTP > Email Test? Here’s a screenshot for the option to get a full error log. This will give us an idea of what might be going on.

    Hi @sanzeeb3 and thank you for your reply.
    My question was if your plugin supports StartTLS as an SMTP command (PHPMailer). Not all SMTP plugins do unfortunately.

    Fortunately, your plugin does. I was testing a number of plugins, and WP Mail SMTP by WPForms didn’t work either, but in hindsight I ran into some TLS cert issues. I fixed those and your plugin sends e-mail using authenticated SMTP and (Start)TLS.

    I’ve marked this as resolved, thank you.
