I got this error during install and now I cant get mta up and running.

Code:
Operations logged to /tmp/zmsetup.log.3225
Setting defaults...     MX: zimbra.****.com (194.21.214.176)

My host file is as follows:
Code:
127.0.0.1       localhost.localdomain   localhost
194.21.214.176   zimbra.****.com       mail
# The following lines are desirable for IPv6 capable hosts
::1     ip6-localhost ip6-loopback
fe00::0 ip6-localnet
ff00::0 ip6-mcastprefix
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters
ff02::3 ip6-allhosts
I dont get the conflic as its the same interface and it's directed to the same spot 127.0.0.1 is the localhost as is 194.21.214.176. I'm using debian and the debian binaries.
