Hi All ,

We are using Exim mail server at present and we are having critical problem in it , now suppose i am installing a q mail on this server , how can shift my existing mails from Exim to q mail , as i am not able to send receive mails from exim mail server and there are thousands of mail in /var/spool/mail directories...

One more question i want to ask is it possible if i am making a new server , as i am having my web site is loaded on one live server and exim mail server is also on this live server , now suppose i want to make a two different server for this is it possible , i am having only one live ip with is bind with my web site domain + plus my exim ..may i need to buy a new live ip ,,,will it work for my same domain ..(abc.com ) I mean if i buy a new live ip may how can i bind it with my company name for my mail service ... ( abc.com) ( As one ip can bind with only one web domain ) ...

What I'm thinking about is you must at least make Exim run for you to be able to flush all deferred mails and sent to its respective recipients before switching to another MTA.

When it comes to user inboxes' messages, your clients can retrieve everything as long as your POP3 is working with its relevant users' authentication mechanism and still accessible through your IP and no messages would be lost. Your POP3 runs independently with your Exim SMTP.

To make both your web and mail service accessible through a single IP, simply request your DNS host to add CNAME( in your domain's DNS zone file. (Showing only here the relevant portions.)

John,

Are you using a firewall/gateway? If so then look at the configuration on it to send ports 25, 110, 143 to one internal-ip and port 80 to another internal-ip. I am using a LinkSys Firewall Gateway appliance at work but you could do it with a linux box configured as a gateway. You should not need another external fixed ip.
