|Determine the "identity" of your emails. Set with SAM the sender, signature and folder for sent items with the help of rules.
This sample checks an e-mail's size before sending. You can cancel if it exceeds a pre-determined size. Here the limit is set to 10,000 bytes, which is a little less than 10kb. Adjust the value if needed.
