[8.940013] POP3 proxy (enable/disable) download emails

Hi All

I had pop3 proxy configured and working for some time. Then I've decided to turn it off. Today I've decided to turn it on again and I've noticed that my outlook client download all emails (old ones)

According to the POP3 stored messages (mail manager) I had 1500 stored messages (before enabling the functionality). Now I have 300 which I presume are the stored emails for the other clients

I am not sure if this is a bug but why are my emails downloaded to the client once I re enable the pop3 proxy? The emails had been successfully downloaded few weeks ago (just before I've decided to turn the functionality off)

Also how can I delete the stored messages?

I found this relevant thread as well but there is no solution provided: http://www.astaro.org/astaro-gateway...ow-delete.html

Thanks
