Can't send/receive e-mail with my mailer at dynamic address rakot.ath.cx. It is no MX record. Ddclient.conf: daemon=300 mail=root mail-failure=root pid=/var/run/ddclient.pid ssl=yes use=if, if=tun0 login= password= server=members.dyndns.org protocol=dyndns2 mx=rakot.ath.cx backupmx=yes wildcard=yes rakot.ath.cx What can i do to fix MX? Thanks.

An MX record is not required for sending email, the problem is usually that you are trying to send email directly from a dynamic IP, rather than relaying it through your ISP or another mail server.
If you're running your own mail server you'll need to create a second hostname that resolves to the same IP address. Then you'll need to set it as the MX for
rakot.ath.cx (since Dynamic DNS doesn't allow you to set a hostname as it's own MX). Otherwise set the MX to the hostname of the mail server for your domain.
