    Default Problems sending email using any email client for some domain

    Server has:
    P4-2.8 / 1 GB RAM (mostly unused) / CentOS 4.3 / Zimbra Open Source 3.1.3

    Total domains: 4,,,

    cat /etc/hosts: localhost.localdomain localhost sub

    I can't send emails from using Microsoft Outlook.

    Error: Server Response 554 - Relay Access Denied

    cat /var/log/zimbra.log | grep postfix | grep domain2 yields an error of the following form:

    Jun 26 12:44:00 226 postfix/smtpd[7346]: NOQUEUE: reject: RCPT from unknown[]: 554 <>: Relay access denied; from=<> to=<> proto=ESMTP helo=<bzaveri> is my IP. is the Recipient to whom mail is to be sent

    I also did the following:

    [zimbra@sub ~]$ postconf smtpd_recipient_restrictions
    smtpd_recipient_restrictions = reject_non_fqdn_recipient, permit_sasl_authenticated, permit_mynetworks, reject_invalid_hostname, reject_non_fqdn_sender, reject_unauth_destination, permit
    [zimbra@sub ~]$ cat /opt/zimbra/cyrus-sasl/etc/
    zimbra_url: %%zimbraMtaAuthURL%%
    zimbra_cert_file: /opt/zimbra/conf/smtpd.crt
    zimbra_cert_check: off
    [zimbra@sub ~]$ cat /opt/zimbra/cyrus-sasl/etc/saslauthd.conf
    zimbra_cert_file: /opt/zimbra/conf/smtpd.crt
    zimbra_cert_check: off


    1. SMTP Authentication is enabled
    2. This server requires a secure connection checked on the advanced tab for incoming mail server
    3. This server requires a secure connection NOT checked on the advanced tab for outgoing mail server (if I check this, I get another error).
    4. Another thing is that everytime I try to retrieve emails I get the SSL prompt asking me if I want to proceed. This is a fresh install but on other systems where I installed Zimbra, it only asks the first time I try to connect, not everytime.

    Help :-)
