Send mail using System.Web.Mail fails w/ m.BodyFormat=MailFormat.H

[Ryan]

Hi,

I receive an access denied error (see below) when attempting to send an
email with BodyFormat=MailFormat.Html from an asp.net page. Exactly the same
code works fine in a console application, and also succeeds from the asp.net
page with BodyFormat=MailFormat.Text.

I've recently upgraded from W2K SP4 to WinXP SP2 and am using .Net Framework
v1.1 SP1. The code worked fine under W2K SP4.

Any ideas? I've seen the same problem posted on the web a few times but
have not seen a response.

The error:
Server Error in '/WebMailTest' Application.

Thanks - that site was my first port of call when I experienced the problem
but to no avail (although someone did raise exactly the same question it
remains unanswered).

Hi Ryan,

I think this should be a environment specific issue. Are you encountering
the same problem on some other server? Also, are you sending the email
through exchange server or a custom smtp server and does that server
require authentication. In addition, since console application and ASP.NET
application are running under differernt process identity and logon
session, I think you can also try make your ASP.NET page use windows
authenticaion and impersonate the client user to see whether this can make
the application work. If work, the problem should be related to the
executing security identity.
