SASL DIGEST-MD5 authentication failed: another step is needed in authentication

[bwelker]

Hallo,

ich bekomme folgenden Fehler wenn man versucht Mails via smtp zu verschicken:

SASL DIGEST-MD5 authentication failed: another step is needed in authentication

Was kann ich da tun? Ich hab die RC4 installiert und das Problem kam ohne zutun auf. Heute Morgen war verschicken noch möglich.
