[Evolution] Evolution Cache Limit

[Murray Trainer <mtrainer central-data net>]

Hi All,

We have a user using Evolution with a pop3 account.  He was wondering
where all his disk space was being used.  Turned out half of the space
being used was under the following folder:

~/.evolution/mail/pop/user mail domain/cache

Is there a limit to the amount of disk space that Evolution can use for
caching or does it do any automatic cleaning up of cache files?  A cache
limit setting similar to web browsers would be useful for situations
such as ours where users have fixed disk quotas. 

Thanks

Murray
