Re: [cobalt-users] RaQ4 - CPU overload

[ajongsma <andries.jongsma@xxxxxxxxxxx>]

Hmm, another strange thing about qpopper. I allways thought that qpopper
would only copy the new message at the bottom of the mailbox of a specific
user su the load would only be a little bit higher with a non-empty mailbox.
As you can see the users are "fairly" educated by now....

I checked all mailboxes wich aren't empty:
