[Evolution] clearing of cache

["J.L. Blom" <jlblom neuroweave nl>]

I'm making a backup of my large set of E-mails to transfer to another
system using the old-fashioned way by storing everything an a tarred
archive (I'm still on 2.10.3, the latest on FC7 where backup is not
available). However, I don't need the cache directories to be saved. How
do I remove these?
Another thing is that the camel_certs file (or directory?) does not
exist on my system. Is that for newer systems than 2.10?
Thanks in advance,
Joep
