Can Messaging Server support two instances with on store?
Hi All
I encountered this problem:
A big LAN plan to improve it's network connection speed, the ip address in this LAN are all real ipv4 address not like 192.168.*.* and so on. But the firewall between the LAN and internet is bottleneck of net speed. People outside the LAN want to improve email deliver speed,such as webmail, POP3,SMTP speed.
so we wana apply a new network connection line inject this LAN. these new IP addresses (we say that is 123.123.123.123) will have fast speed and no need to pass the firewall.
My question is: Can I run two instances which have two IP, one have the ip address in LAN (such as 222.2.2.2) and another have the new ip 123.123.123.123.
These two instances have the same domain and share the same store.
then DNS server change the MX record to
MX5222.2.2.2
MX10123.123.123.123
when emails arrive this domain they can go to ether of the two ip addresses.and arrive in the same mail box.
when people use POP3,they can connect to ether 222.2.2.2 or 123.123.123.123 to got their emails . and SMTP did the same work to send email.
Can messaging server support this configuration?
Thanks very much

Hi,
I am a bit confused why you need two instances of messaging server? From what you have described you are going to have two IP addresses with which to contact the messaging server services (SMTP & POP & WebMail I assume).
By default messaging server listens on all network interfaces, so as long as the underlying OS can communicate to the IP addresses then messaging server will as well. You may need to modify some setting such as the 'internal' IP address range in the MTA mapping file to allow relaying of emails - but that should be about it.
An example of this already in place is the loopback interface (running on 127.0.0.1). When you are logged into the host of the messaging server instance, you should be able to connect to the POP port by running:
telnet 127.0.0.1 110

Hi shane_hjorth, Thanks to your reply.
It's did my mistake to ask this wrong problem :( . When typing this question, I'm thinking about run two messaging servers on two machines. then found that use shared disk store is a little complex, so change that to two instances. :)
I know the web services will listen on all IP in the SUN box.
so can double IP addresses fix this network slow problem? Will all the emails arrive correctly, Should I have to change the route table so the local email use which way to sent out? you know other email server will reverse parse my email and maybe consider my email as spam.
