has someone working email notification on rockstor 4.0.4?
I did try several smtp outgoing servers (both linux and windows server) and it is not working as is.
postfix/smtp: warning: SASL authentication failure: GSSAPI Error: Unspecified GSS failure. Minor code may provide more information (No Kerberos credentials available (default cache: DIR:/run/user/51/krb5cc))
This means the remote server and rocstors postfix negotiated KRB5 authentication (or another digest mechanism sometimes) that it is not working.
As a temporary fix I added this line to /etc/postfix/main.cf:
smtp_sasl_mechanism_filter = plain, login
It is working now.
What is your experience with email notification on Rockstor 4.0.4?
