Hi,
It looks like your email settings are actually set to MAPI. Please recheck and reset to Direct.
If you do use MAPI, you can resolve the security access for each email by getting your Adagio Consultant to download and install (and test) a shareware called ClickYes. It auto-answers the MAPI prompts with a simulated "Yes" keystroke, and so there are no delays.
Almost everyone using MAPI method should be using ClickYes to resolve the confirmation delays on emails being sent. Best Practices 101. :))
Best,
Brian
