If the SMTP server is not running:

- ASP.NET: SmtpMail.Send throws an exception.
- Classic ASP: CDO.Message send places a message file in the mailroot/pickup folder that is sent out when the server is restarted.

I want the classic ASP behaviour so I tried to workaround this in ASP.NET by adding a reference to CDO.DLL so I could create a CDO.MessageClass object. This works, but the behavior is identical to SmtpMail.Send. Same result if I instantiate CDO.Message instead of CDO.MessageClass.

I also find that under .NET 1.1 I have to set the SMTP Server access to allow anonymous access. I've tried doning authentication but I'm going wrong somewhere. I'm using my system adminstrator logon and password but still get authentication errors. CDO.Message send under classic ASP is not affected.

Anyone have a clue?

Thanks,

Can you post the exact exception that it throws?

I don't remember the exact exception but the solution is to use the Fields property of SmtpMail:
Set sendusing and postusing to 'pickup'.
Set smtpserverpickupdirectory and nntpserverpickupdirectory, typically to "C:\InetPub\mailroot\Pickup".
Set flushbuffersonwrite to True (not strictly necessary I don't think)

Here's my theory of how this came about.
1. Under Classic ASP, CDO.Message defaults to the above settings.
2. SmtpMail under the 1.0 Framework did not allow access to the Fields collection, so MS kept the same default settings for the wrapped CDO Message object.
3. SmtpMail under the 1.1 Framework does allow access to the Fields collection, so MS decided the defaults weren't appropriate now that users had access to the fields collection.

Unfortunately they apparently didn't document any of this, so unless you're already familiar with CDO beyond just taking the defaults under Classic ASP and then the SmtpMail defaults under the 1.0 framework, then you're pretty much clueless as to what's going on under 1.1. I didn't even know the fields collection existed. When you go to the 1.1 Framework MSDN documentation for SmtpMail.Fields you find 'to be defined'.

Hi Richard,

I think you are referring to MailMessage class's Field property.

Being not sure about the exception that you faced, I am not sure where to point you to. But I think this might help you as to know how to access FIELDs collection.
