This did help 50%. POP3 works. I can log in and retrieve mail. However I'm gettin a different error now from the SMTP server: Server returned error: "DNS Error: DNS type 'aaaa' lookup of smtp.mysticrealms.ddns.net responded with code NXDOMAIN DNS type 'a' lookup of smtp.mysticrealms.ddns.net responded with code NXDOMAIN, code: 553 I think this means that the SMTP server name is not right. the POP3 server is pop3.mysticrealms.ddns.net and works. I don't understand why the SMTP is wrong.
