Fw: Kolab Service Does not Start/No Emails Can be Sent/Received

Skale,

The cyrus-imapd daemon seems to be up but sick:

What might be leading to these SASL/ldap errors after the yum update? 

Thanks,
Bob

Hi Bob,
it seems, that the cyrus imapd failed to start.
It the central component. Wihtout a running and working imapd, no 
service could function !
So check the imapd logfiles and report back.
Btw. every service can  be put in debug mode using the "-d" flag by 
changing the /etc/default/* defaults file.
For cyrus, you might wann try:
# Set this to 1 or higher to enable debugging on cyrmaster
CYRUS_VERBOSE=1

Best regards
Franz
