$ host -t mx acumen-corp.com acumen-corp.com mail is handled by 10 216.90.94.145. acumen-corp.com mail is handled by 20 mail2.acumen-corp.com. acumen-corp.com mail is handled by 5 mail.acumen-corp.com. MX records MUST point to hostnames, NOT IP addresses. The MX at priority 10 is therefore wrong. -- Anand Buddhdev http://anand.org ------------------------------------------------------- This SF.NET email is sponsored by: eBay Great deals on office technology -- on eBay now!
