Critical Message not sent in webclient and Zimbra Desktop

[senthilkumar84_2000]

Hi,

Am using Zimbra zcs 5.11 GA, recently my ISP changed the IP series and i reconfigured my mail server with new IP, /etc/hosts file, but while am trying to send mail from web client and also in Zimbra Desktop am getting following error

Message not sent; one or more addresses were not accepted.
Rejected addresses: somebody@gmail.com

But am able to send the same mail from Outlook. i didn't change any settings in any other file except the above mentioned file.

Please help me to fix

Thanks in advance

After changing the IP address and DNS, be sure to change the ZimbraMtaMyNetworks to add the new server IP.

/var/log/zimbra.log shows "relay access denied" when sending from the webmail or desktop client.

You could view the current allowed networks by running this command as the zimbra user:

postconf mynetworks
