Hi, It used to work but we can reevaluate that one later i think. I will consider the send rate thing because you are right, some servers dont like being spammed. Where I work we use a C++ script to send directly via smtp which works well however buggy. One of the reasons we decided to use a scheduled email send is that the cron handles the send and not the clients machine.
Myself and Tim are away this weekend from tonight so will have to look at it next week.
thanks for the feedback.
Sean
