    hello awesome people
    i'm receiving this error when sending to couple of people both in Lebanon - i am able to send normally to other people

    "the mail server refused to talk to me: 421 Downstream server error"

    the bounce mail arrives after 5-6 hours of sending the email .. is it an issue from my side or the recipient ?!

    thank you
