Support » Plugin: WP Gmail SMTP » HELO/EHLO argument is invalid

  • Hi,

    I have configured the oauth correctly, but when I send a test e-mail I get the following error:

    CLIENT -> SERVER: EHLO ~^(.*)$
    SMTP -> get_lines(): $data is ""
    SMTP -> get_lines(): $str is "501-5.5.4 HELO/EHLO argument "~^(.*)$" invalid, closing connection."
    SMTP -> get_lines(): $data is "501-5.5.4 HELO/EHLO argument "~^(.*)$" invalid, closing connection."
    SMTP -> get_lines(): $str is "501 5.5.4 https://support.google.com/mail/?p=helo ia7sm104254691wjb.23 - gsmtp"
    SERVER -> CLIENT: 501-5.5.4 HELO/EHLO argument "~^(.*)$" invalid, closing connection.501 5.5.4 https://support.google.com/mail/?p=helo ia7sm104254691wjb.23 - gsmtp

    Any suggestion?

    Thanks,
    Stefano
