Hello! I'm new here, I'm very happy to join this group and to be the one of Knownhost's customers. Yesterday I had many problems in setting firewall and mail function, when I submitted the ticket form almost after 1 hour I received the reply to solved my question each time, thank you very much Knownhost. Another thing is not about this subject I'm having a trouble because of Yahoo deny the mails that send from my IP, could somebody help me to test that? My server can send mails to other email provider ex:Gmail, hotmail but Yahoo don't receive the mail from my server, anyone else have the same problem as me?
