[IMail Forum] Resolving mail addresses locally

[Nelson Winters]

My company is in the process of migrating our clients from our old mail server (MAIL1) to our new Imail server (MAIL2).  The two are located on different machines.  Our DNS is on the same server as MAIL1.   I've added a virtual host for one of our client to MAIL2, but have not added their users yet.  The MX record for their domain still points to MAIL1.  However he received an error message from MAIL2, which I would have thought shouldn't be talking to anyone for this account since the DNS still points to MAIL1.   The only thing I can think of is that maybe a user that is using MAIL2 (such as myself) is trying to send him messages and the server is trying to resolve it locally before checking the DNS.  Does anyone know if this is correct.   Sorry if I'm being to vague here.  I'm still an IMail newbie.   Thanks,   Nelson
