mail

#1

I have two Nethserver insallations on different Locations. The one on location B uses the one of location A as Mailrelayhost. this worked until reacently without any Problem. After a update yesterday I get for each mail trying tobe sent the following messages in my maillog:

postfix/smtp[23960]: warning: SASL authentication failure: GSSAPI Error: Unspecified GSS failure. Minor code may provide more information (No Kerberos credentials available (default cache: KEYRING:persistent:89))
