Right, I really want to ditch postfix
for good except on my main server that does Majordomo and
Virtual DNS, we are seeing high load that I am forced to switch back
to postfix.

MY configure file reads:



primary_hostname = primary server



domainlist local_domains = @:<huge list of Domain names>

domainlist relay_to_domains =
hostlist relay_from_hosts = 127.0.0.1 : 204.209.81.0/24 : 192.168.0.0/16 : 208.118.93.0/24: 208.118.94.0/24


trusted_users = exim : majordomo


acl_smtp_rcpt = acl_check_rcpt
acl_smtp_data = acl_check_data

# acl_check_data access control list (see below).

av_scanner = clamd:127.0.0.1 3310


# For spam scanning, there is a similar option that defines the interface to
# SpamAssassin. You do not need to set this if you are using the default, which
# is shown in this commented example. As for virus scanning, you must also
# modify the acl_check_data access control list to enable spam scanning.

spamd_address = 127.0.0.1 783



# Allow any client to use TLS.

tls_advertise_hosts = *

tls_certificate = /usr/exim/exim.crt
tls_privatekey = /usr/exim/exim.key


daemon_smtp_ports = 25 : 465 : 587
tls_on_connect_ports = 465

# qualify_domain =

# allow_domain_literals



never_users = root


host_lookup = *



rfc1413_hosts = *
rfc1413_query_timeout = 5s


#
# percent_hack_domains =

ignore_bounce_errors_after = 2d

auto_thaw = 1m


# split_spool_directory = true

#spool_directory = /var/spool/exim.in
#log_file_path=/var/log/exim/%s

Right, where do I start? No problem on sec server.

Also running current Clamav and SpamAssassin
