Hello, I've decided to leave webmail round cube out, I removed it. Just using a email client on the desktop. Debian is running good further ISPconfig. Please help to understand this correct. So at the Provider where I have the domain there the DNS have A records pointing towards the IP at strato, so like Code: @ A 184.108.40.206 mail A 220.127.116.11 pop A 18.104.22.168 smtp A 22.214.171.124 @ MX 126.96.36.199 I only changed the IP addresses there. In ISPconfig I've added an Email domain: Code: server: h123456.stratoserver.net client: blablabla Domain: mywebsite.com Spamfilter: Normal created a mailbox: Code: [email protected] Password: bliebblieb It does not work with desktop email client. Not sure if needed, but created a DNS zone in ISPconfig and only added MX record Code: server: stratoserver zone: mywebsite.com NS: NS1.ywebsite.com added MX record Code: hostname: mywebsite.com mailserver hostname: mail.mywebsite.com active is on And I tried the wizard, but I must be putting something wrong. Still not working. Can please anyone explain what I'm doing wrong? Thanks a lot.
