Hallo,

 

ich habe seit ?ber einem Jahr einen Mailserver unter froxlor laufen - bisher keine Probleme. Seit zwei Tagen kann ich aber kaum noch Mials an externe Domains schicken - auch an Adressen, an die das bisher problemlos ging.

 

Die fremden MX Server lehnen meinen Mailer ab und ich erhalte prompt folgende Reaktion (mailadressen ge?ndert) - es geht nicht nur um posteo,de, auch um andere

Zum Senden musst du genau wie beim Empfangen mit benutzer und passwort eingeloggt sein. pr?fe ob dein e-mail client auch f?r SMTP die authentifizierung nutzt
