Mapi x.400 VB.Net

Hi all,

Bit of a newbie on here so bear with me.

I have developed an ASP.Net site for a client, and the requirement has appeared
to send emails automatically, to an Exchange 5.5 server (on another domain)
using MAPI (server is x.400).

Does any have any pointers on how to do this (VB or C# examples would be
nice)!

Regards

Jules

Hi,

MAPI is not supported in a .NET process. It's memory management collides
with the .NET garbage collector.

You might want to consider enabling SMTP on the Exchange 5.5 and send the
mails through SMTP.

Kind regards,
Henning Krause

Hi Henning,

Thanks for the reply. Unfortunately, my client only use x.400 (Government
site).

Any ideas?

Regards

Jules

What about CDO? I think there has been quite a bit of C# development
there (or with Redemption www.dimastar.com). I'm no pro there, but I
believe it gets around the MAPI memory constraints being discussed. If
I'm wrong please correct me.

Thanks!!

CDO1.21 is just a wrapper for Extended MAPI, so has the same problems --
see http://support.microsoft.com/kb/813349.

CDONTS/CDOSYS are wrappers for SMTP, which isn't X.400.
