Sending Email using MAPI33

I am trying to use MAPI33 to send an email over a MAPI profile without triggering the security prompt. Outlook Redemption does this to a limited extent but requires office and isn't as powerful.
I will award 500 points to the first person to come up with complete working C# code that accomplishes this task using the MAPI33 library.

The function needs to be able to take the standard message fields such as To, CC, BCC, Subject, Body, and some form of attachments.
If its any help, I am working with the source code sample provided at http://g8.cx/mapi so if you need to take advantage of any functions in the MapiWrapper.cs file, you can.

BTW, don't know if you've seen this link. It's obviously not MAPI33, but it helped me get as far as I did:

Great code muellerfan. I noticed you pass an outlook interop app object as an argument but appobj isn't being used. I guess this is something related to another bit of code of yours? I was able to remove that argument and the code worked just fine.

Thanks for your help, A+ Response!

Thank you! It was a challenge. You are right about appobj being related to another bit of code that I'm actually not even using anymore. I guess I can get rid of that argument.
Thanks!

Hi Do you know what happened? When i am using above code?
Thanks!

An unhandled exception of type 'System.MissingMethodException' occurred in finaltest.exe

Additional information: Method not found: MAPI33.Error __MAPI33__INTERNALS__.MAPITable.QueryRows(Int32, FLAGS, MAPI33.MapiTypes.Value[,] ByRef).

Hi,

How do I get the current user SMTP address in outlook 2003. See the code below but I get the erorr InvaliEntyId.

Thanks,
Dave
