I don't believe that setting up a MX record for the new domain name will solve your issue. Although multiple mail exchangers can service a domain, each MX record contains a preference number ranging from 0 through 65,535. If two MX resource records have different preference numbers, the mail exchanger with the lower preference number handles mail for the domain. The mail exchanger with the higher preference number receives incoming mail only if the preferred mail exchanger is unavailable. If two or more mail exchangers have the same preference number, DNS responds in round-robin fashion to MX queries, balancing the load among the mail exchangers. There are other solutions available, depending upon your configuration of course. For example, several Smartlist mailing lists are going to be moved within our domain over to a Listserv box, once we address several issues on Listserv that are still outstanding. To do this, we use mail mappings on our firewall mail server to change an internal email address to an external email address. Any incoming mail that matches an external mapping name is changed to the corresponding internal mapping name. Similarly, any outgoing mail that matches an internal mapping name is changed to the corresponding external mapping name. So a sample mapping would have: [log in to unmask] presently maps internally to [log in to unmask] once we go on-line with Listserv [log in to unmask] will map internally to [log in to unmask] So subscription and other list requests will continue to come to [log in to unmask] We then control internally where they're delivered to. Another option will be to create a mail alias within your domain. Unlike mail mappings, which are bi-directional, aliases only work for inbound traffic. The end result would be the same as my example above, except it only works inbound. Which sounds to me like what you are looking to do. Dennis W.

Hello all, We are in the process of migrating our listserv to an other server that will use a different domain name. What I would like to know is if I can have our existing users send to mail to the original domain lists.ittoolbox.com and use a MX record to forward them to our new domain name. If this is possible how will listserv deal with it? I would appreciate any feed back.
