System.Web.Mail.SmtpMail.Send throws Could not access 'CDO.Message' object.

[DotNetGruven]

System.Web.Mail.SmtpMail.SmtpServer = "10.50.7.160";

System.Web.Mail.SmtpMail.Send(mailMessage.From, mailMessage.To,
mailMessage.Subject, mailMessage.Body);


What could cause this exception to be thrown in code behind on an XP Pro
development machine?

- Do I need to install CDONTS? Something else??
- Is there some configuration some where??

TIA,
geo

Hi Geo,

From your description, you encountered "Could not access 'CDO.Message'
object" error when using System.Web.Mail smtp component to send mail?

Based on my experience, such problem is likely caused by the SmtpServer is
not accessable. I Would you have a further check to see whether the
smtpserver you set is avaliable? Also, you can try accessing it via its
server name instead. Or is possible try testing using another smtp server
which is guarantee to work.

In addition, here is a weblink to the System.Web.Mail's FAQ sites which
contains many helpful faqs.

Hope also helpful. Thanks.

System.Web.Mail.SmtpMail.Send uses CDOSYS not CDONTS so you don't need to install it. You normally get that error if there is a problem with your EmailTo or EmailFrom fields such as

1) Email address is malforme
2) Your smtp server is rejecting the email addresses because of domain security issue

S

1) Make sure your email address is well forme
2) Make sure your smtp server can accept emails from specified domain

Cheers,

Mark.
