I have just set up a new email account [email protected] (not its real name) and the server name (both incoming and outgoing) is [email protected] I can't receive emails - the sender receives a message along the lines of "can't find sh.com.au". I also can't send emails - I get a message along the lines "this is a temporary problem. Please try again later." I've had this problem for several days now so I don't think it is temporary. I have attached a screenprint of the SMTP settings. I have also attached a screenprint of the Account Settings and I think it provides a clue. In the Account Settings, the SMTP Server is described as "[email protected] - [email protected]". My mail provider is Netregistry (that's the ezyreg.com domain). My ISP is Belong but they don't provide email. My antivirus software is McAfee Total Protection and I use its Firewall. My computer is running Windows 7. I am using Thunderbird 60.6.1 (32-bit). I hope you can help. I searched through about 16 pages of support answers that I thought might have been relevant, but with no success. Thanking you in anticipation, Shirley
