web client not sending or receiving mail

[eaperezh]

Hi, my configuration is as follows:
centos 4.2 rpm with all in defaults
caching nameserver
/etc/hosts
127.0.0.1 localhost.localdomain localhost
192.168.93.128 internal.localdomain internal
200.75.247.195 centos.myvnc.com

the address 200.75.247.195 is the NATed address controlled by the firewall.

is there any additional settings that must be modified to allow sending/receive mails for the MTA? as well as the web client?

when sending with the web client i got this error:

in global settings the webmail mta hostname is localhost
but in the server mta settings is centos.myvnc.com

[marcmac]

Can the host access centos.myvnc.com (the public IP) on port 25? Does that forward back to the host on port 25? Try telnetting from the zimbra host to the public IP on port 25, what happens?

Does the account exist in the system? I assume your domain is centos.myvnc.com. What do you get from
zmprov ga eperez@centos.myvnc.com | grep MailTransport

If that's lmtp://centos.myvnc.com:7025
make sure that you can get from the zimbra server to the public IP on port 7025, and it gets forwarded back to the zimbra server.

WHat do you get from:
zmprov gs servername | grep zimbraSmtpHostname
