[IMail Forum] Listserv Question

[Brent Watson]

I am setting up my first listserv and am having difficulties.  The client's email is hosted at their site and is set up in the MX record for the top level domain - [EMAIL PROTECTED].  I need to host the listserv on our IMail server (separate from the client's site) and am using the sub-domain [EMAIL PROTECTED] as the address.  We have set up the MX record for this and lists.domain.com resolves to the proper IP address on our machine when pinged.   The weird thing is the interaction between the top level domain and the sub-domain.  When sending something to lists.domain.com it is returned from the client's email server at domain.com.   I am assuming this is a routing problem and is somehow tied in with the MX record.  Is there anything I need to do in IMail when trying to have regular mail routed to one server while setting up a sub-domain to handle the listserv on another server?  Also, any thoughts on setting up the MX record (not my specialty - it's being handled by someone else) for this scenario would be appreciated.   Thanks for the help,   Brent Watson
