That would fit the problem that we are seeing here. Although everything is
set to delete read mails on the server it never happens. I'll already
added quite some debug output and made small changes (trying to flush the
changes iirc) but nothing helped. My current believe is that there is a
bug in the PHP POP3 module.
I never monitored the network traffic but what we see is an enourmous CPU
usage. The PHP script downloading and parsing the message is probably not
that memory efficient.
This is one of the few outstanding issues with Eventum we'd like to
resolved. We are otherwise using it successfully for several months now.
