Test Email Gives successful message for Invalid Email

  • Hi,

    I am using this plugin for one of our website below:

    Trailers For Sale

    I an using hosting server SMTP configuration… I needed information for those emails address send mail failed… But using wp_mail I am always getting success even for invalid email address. Also at test panel I can see success msg even for invalid email address like [email protected]
    here is debug log

  • Hi, this is the first time I hear about this issue. So you are saying that typing in the wrong e-mail address you are successfully sending the e-mails? Is this correct?

    Thank you

    how that is possible… SMTP server cannot send email to an invalid email address…

    What I am saying…
    I am getting test mail successful message for an invalid email from plugin test panel… that means there is no checking from plugin side if it is valid email or if SMTP server rejects that invalid email… do It is from the plugin test email panel… at actual SMTP server was not able to deliver that email…

    Thanks

    Hi.

    The plugin cannot check if SMTP actually delivered email or not. It can just check if SMTP server accepted the email for the delivery (which it does). E.g. this test shows whether communication between your website and SMTP server can be established. Whatever happens to the email after than cannot be tracked or handled by the plugin. Properly configured SMTP server (not the plugin, but the server itself) should bounce undelivered emails back to the sender or to some pre-configured email.

    According to the log you provided, the plugin can communicate with your SMTP server just fine and it accepts the test message, so there seems to be no issues with the plugin here.
