moin,
beim Versuch eine E-Mail zu senden nach außen, bekomme ich ein authentication failure. Die E-Mails was vom Server kommen wie zb. logcheck oder wenn ich eine E-Mail an mich selbst sende funktioniert. Auf dem Server habe ich Postfix+Dovecot+sasl2 laufen.
Ich komme nicht darauf an, was das liegen kann, hat jemand eine Idee an was das liegen kann? LG.
