Hi all,
I am trying to build our new architecture and I am having some troubles
with making email work right.
Here is the design:
Email Gateway relays email to/from Email server
The email gateway scans emails for viruses and spam and then forwards
the mail to email server. Both are using exim4. On the gateway I have
clam antivirus combined with spamassasin - using amavisd-new.
Here is what I have for
begin routers
#this is the first router
amavis:
~ driver = manualroute
~ condition = "${if or {{eq {$interface_port}{10025}} \
~ {eq {$received_protocol}{spam-scanned}} \
~ {eq {$sender_address}{}} \
~ }{0}{1}}"
~ domains = +local_domains
~ transport = amavis
~ route_list = "* localhost byname"
~ self = send
begin transports
amavis:
~ driver = smtp
~ port = 10024
~ allow_localhost
This works perfect for scanning for viruses and spam as amavis is
listening on 10024 port and I have made exim to listen on 10025 for
incoming mail too.
The problem is that I don't know what to do next and how to relay the
mail to/from the central mail server.
I read the exim4 FAQ's and found routers for relaying the mail to
another server. Is it enough to just put a router like this after the
first router for amavis:
send_to_gateway:
~ driver = manualroute
~ transport = remote_smtp
~ route_list = * central.server.host
And can I put IP address(not FQDN) in the place of 'central.server.host'?
