[Skunkworks] Is there a problem with Jambo DNSs?

Hi's, I have a problem with some domains hosted by Jambo as far as the mail exchange is concerned. mxtoolbox.com gives me this... *<mydomain>.co.ke:mx* -mzizi.kenic.OR.ke: A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond I can ping the host from the internet but can see the mail messages won't find the 'post-office'. Someone kindly give me a contact at Jambo who can help me with the same. Regards, Martin
