Thank you very much for your quick reply! I appreciate your help!
FYI, this organization is currently using the POP email that came with their hosting provider. We are setting up Zimbra due to the large amount of email traffic that should be "in house", and the need for a calendar system. In order to prevent any service interruption, we have not altered the A or MX records yet.
One question I do have, is why would Zimbra's MySQL server need to connect via the external host? Why not use localhost?
Here is what you asked for:
cat /etc/hosts
# Do not remove the following line, or various programs
# that require network functionality will fail.
192.168.1.155 mail.fairhavenchurch.org mail
localhost.localdomain localhost
::1 localhost6.localdomain6 localhost6
cat /etc/resolv.conf
search fairhavenchurch.org
nameserver 64.65.223.6
nameserver 64.65.196.6
cat /etc/nsswitch.conf
#
# /etc/nsswitch.conf
#
# An example Name Service Switch config file. This file should be
# sorted with the most-used services at the beginning.
#
# The entry '[NOTFOUND=return]' means that the search for an
# entry should stop if the search in the previous entry turned
# up nothing. Note that if the search failed due to some other reason
# (like no NIS server responding) then the search continues with the
# next entry.
#
# Legal entries are:
#
# nisplus or nis+ Use NIS+ (NIS version 3)
# nis or yp Use NIS (NIS version 2), also called YP
# dns Use DNS (Domain Name Service)
# files Use the local files
# db Use the local database (.db) files
# compat Use NIS on compat mode
# hesiod Use Hesiod for user lookups
# [NOTFOUND=return] Stop searching if not found so far
#
# To use db, put the "db" in front of "files" for entries you want to be
# looked up first in the databases
#
# Example:
#passwd: db files nisplus nis
#shadow: db files nisplus nis
#group: db files nisplus nis
passwd: files
shadow: files
group: files
#hosts: db files nisplus nis dns
hosts: files dns
# Example - obey only what nisplus tells us...
#services: nisplus [NOTFOUND=return] files
#networks: nisplus [NOTFOUND=return] files
#protocols: nisplus [NOTFOUND=return] files
#rpc: nisplus [NOTFOUND=return] files
#ethers: nisplus [NOTFOUND=return] files
#netmasks: nisplus [NOTFOUND=return] files
bootparams: nisplus [NOTFOUND=return] files
ethers: files
netmasks: files
networks: files
protocols: files
rpc: files
services: files
netgroup: nisplus
publickey: nisplus
automount: files nisplus
