    i'm trying to send a mail to yahoo or to gmail,but here is what i get.......


    This is the mail system at host myname.dyndns.org.

    I'm sorry to have to inform you that your message could not
    be delivered to one or more recipients. It's attached below.
    For further assistance, please send mail to postmaster.

    If you do so, please include this problem report. You can
    delete your own text from the attached returned message.

    The mail system

    : host gmail-smtp-in.l.google.com[209.85.220.31]
    said: 550-5.7.1 [79.166.147.226] The IP you're using to send mail is not
    authorized to 550-5.7.1 send email directly to our servers. Please use the
    SMTP relay at your 550-5.7.1 service provider instead. Learn more at
    http://mail.google 550 5.7.1 .com/support/bin/answer.py?answer=10336
    7si6527754fxm.31 (in reply to end of DATA command)


    the mail returns as undelivered from gmail and it stucks as deferred from yahoo......

    is there any way to fix it or they both don't like dyndns?

    If you go to the error page mentioned in your post above it will give you the details of why your mail doesn't get delivered and what you should do about it, this isn't a problem with Zimbra.

    A lot of mail servers won't accept mail from a dynamic IP because that's what spammers use. You'll have to relay your outgoing mail through your ISPs mail server, read the following article an what you need to do (again, this isn't a Zimbra problem): Outgoing SMTP Authentication - Zimbra :: Wiki
