First of all hi, glad to be joining this community. Well i sucefully installed centOS following the great guide made by Falko Timme. Everything works smoothly except the fact that i cannot receive emails, i've searched through the forums for help basides the fact of finding a lot of similar threads i could not fix the problem, so any help here will be very apreciated. I'm no expert in tcp and internet stuff so i do not really understand all the Co-Domains, DNS, Records settings so i'm really confusing about setting things up. Just to set things simple, I've registered a domain, let's say it's www.xyz.com and everything works fine, i've created an email account called email@example.com, i can sucefully log in to it using Uebimiau, can send but not receive emails. Keep in mind that all my dns, records and co-domains have no settings, i've tried some settings myself, all non-working, and ended up clearing them all to start things from scratch. Now when i try to send emails to firstname.lastname@example.org using a gmail.com account i get the email back saying: PERM_FAILURE: DNS Error: DNS server returned answer with no data. Any sugestions? Thanks.
