I have a few concerns about outgoing emial sent from an exchange-server behind Astro. My grilfriend has sent a few emails with photos as attachments but they are sent outbound with about 10Kb/sec.
I have disabled the [Scan relayed (outgoing) messages]
I have disabled the QoS on the external NIC (that gave a few minor boosts)
Exhcange smtp took about 2,5 hours to sent 6 emails with a total amount of 20MB. This While I have a 1Mbit upload connection.
Why is the outbound connection so terrifying slow? And what can be done to improve the bandwith?
