Thank you I will read this today. It looks very useful.
Sorry for the additional question, perhaps I should start a new thread but you mention the MTA.
Where can I find any info about the scalability of the ACS MTA? This is a very important point for my company. We have deployed 8 MTAs at present and with our larger campaigns we send in the region of 2MM emails per hour. Going forward we need to support 3MM++ per hour.
Is this achievable with ACS? Is there an SLA which states this?
