Typing host -t mx ip-solutions.net shows the following result ip-solutions.net MX 10 pony.ip-solutions.net !!! ip-solutions.net MX host pony.ip-solutions.net is not canonical So I'd suggest that your mailer is doing the Right Thing and complaining about the lack of _correct_ MX records. Pony CNAMES to ip-solutions.net. Everything on the right hand side of an MX record should be an A-record. I'm about to say 'read the manual' because I don't know how to fill in MX records utterly properly myself, so: read the bat book. :) Or the RFCs.
