    Default Help with email from/to non Local accounts

    need some help here.
    below is my setup. (replaced actually with dummy names)
    I have an mx record going to
    and is an A record to
    With main domain
    Doamin registered at Purchased only a domain only , no email account.

    I installed Zimbra Network edition 6.0, all in one linux server.
    Sending and receiving internal mail works fine. created multiple account and works fine.

    My problems.
    1. If i send an email from gmail, it comes back with below error
    550 550 #5.1.0 Address rejected
    Looks like my zimbra server is rejecting it.

    2. I open the webUI of an email account. Tried to compose email to my gmail account, i get
    "Invalid address
    554 5.7.2 Relay access denied"

    How to solve these two problem.
    I need to be able send and receive from and to external email accout.
    I read setting up a smtp relay host with password but i cant put in password for all 1000 emplyees we will migrate.

    Appreciate any help.

    Welcome to the forums

    Check /var/log/zimbra.log for any error messages from Postfix for when a email is received. Please post the details so we are able to help you.
