Search Again: Re: Mx for Mailserver subdomain From: Michael Date: Friday, February 15, 2002 Time: 4:46:49 pm Why does Men & Mice do it like this: > lists.menandmice.com. 86400 A 217.151.171.30 > lists.menandmice.com. 86400 MX 10 lists.menandmice.com. ? and is this better than just leaving off the MX record to make DNS simple? What about in the mail delivery - some MTA's want to check the return address to make sure it is deliverable.
