My intial setup was a problem because mail for exotype.com was hitting my LetterRip server and bouncing. >If lists.exotype.com is running a dedicated, SMTP-based list server (e.g. >ListStar), you may have trouble, as it may not know how to forward mail to >the main server for exotype.com.

If mail that should go to mail.exotype.com rather than lists.exotype.com hits it it bounces. <snip> >With the mail server named lists.exotype.com, the MX record is redundant. >If it were named fred, you'd need the MX record for lists.exotype.com, but >since it's named the same as the subdomain, you don't need it. > Oh, really?
