    I phoenix thanks! so

    I tried to find something in google but I did not find information to zimbra, I'd like to know if someone before had this kind of problem.

    I am a little concerned about this.

    Thanks.

    There are several threads in the link I gave you that cover this problem, have a read of them. This isn't a Zimbra specific problem it's a posttfix problem and Zimbra uses Postfix as it's MTA.
