Hi Christoph,

Your solution works! I added /etc/xymon/libs.local.yaml to the client
configuration with the following content:

local config file for the libs test

whitelist: *: - 'dovecot(\.index|-uidlist|\.list\.index)'

This is different from the existing line in /etc/xymon/libs.yaml:

  - 'dovecot(\.index|-uidlist)'

Thank you very much. My Xymon page is green again!

Cheers,

Jaap

... I think we had the same problems (also Debian) and I guess, this
line in our libs.yaml stems from there:

• 'dovecot(\.index|-uidlist|\.list\.index)'

I just compared it to our other servers and this line seems to be
unique in our xymon hosts, so I'm pretty sure it was added to fix
this problem. ...
