Hello,

Please help solve the following problem:

I use fetchmail to get e-mail form external Internet server to internal mail
server every 15 min.

Internal server is not on the internet - it connects via firewall/virus
'proxy' solution.

I am informed of new mail that arrived every 15 min in worst case.

Is there a way to get internal server more up to date, eg that it got
informed of mail incoming to the Internet server ?

Andrej
