[SOLVED] can't send email

[ami_cahyadi]

Hi everyone, i've just installed zimbra on my openSuSE 10.3 box, the installation ran well, the problem is user can't send email to other email account out from my zimbra server. For information, i'm still able to send email to my zimbra account form my yahoo account (my zimbra server able to receive email from outside).
Please help me, i have no idea what's wrong, all the zimbra service is running (I see it from zimbra administration console).

What errors do you see in the log files? Have you disabled AppArmor and/or any firewall on this system? If you are behind a NAT router have you set-up a Split DNS?

thank you so much for your attention,
i found this in zimbra.log :
host b.mx.mail.yahoo.com[66.196.97.250] said: 553 Mail
from ami@teknokrat.ac.id not allowed - 5.7.1 [BL23] Connections not
accepted from IP addresses on Spamhaus XBL; see
553 5.7.1 [BL23] Connections not accepted from IP addresses on Spamhaus XBL - Mail [550] (in reply to MAIL FROM
command)

the same message appear in my zimbra inbox from zimbra mail delivery system.
My zimbra server is not behind NAT, I have disable the firewall and the apparmor.

The problem is identified in the error message you've posted, have you read the error page? You're listed in Spamhaus XBL list because you're on the CBL. What that basically means is that you have a machine on your network that sending Spam and/or viruses, you need to fix that.

If you are not behind a NAT router and are sitting directly on the Internet, do not disable your firewall! Your machine will be wide open. LDAP, SSH and any other services listening.
