Hi, am a newbie to Zimbra, I have setup Zimbra 8.0.7 on CentOS 6.5. I can send and receive mail internally through the domain (domain.com) but can't send or receive mail from external domains (gmail.com and yahoo.com). I am using this site (https://wiki.zimbra.com/wiki/Split_D...ing_is_working) to verify everything is working fine but am having a hard time interpreting the output i get.

These are my output, any assistance would be much appreciated
