Error sending through Exchange server

Aspose.Email Product Family
1

EDIT: aMail (as referenced below) comes from the statement "Imports aMail = Aspose.Network.Mail"

Chances are I'm doing something wrong, so I thought you could tell me where. Smile [:)] I'm trying to connect to our exchange server and send out an email directly from there. I'm assuming by doing it this way, rather than using a virtual SMTP server to send the email, that the headers will look the same as if I had sent the message using Outlook. Please correct me if I am wrong. My code and the error I am receiving follows.

Dim myExchange As New aMail.MailExchangeConnection

myExchange.Host = "xxx.xxx.xxx.xxx"

myExchange.Username = "username"

myExchange.Password = "password"

Dim mySMTP As New aMail.SmtpClient(myExchange)

Dim myEmail As New aMail.MailMessage

myEmail.From = New aMail.MailAddress("from@from.com")

myEmail.To.Add(New aMail.MailAddress("to@to.com"))

myEmail.Subject = "Test email"

myEmail.Body = New aMail.TextPlainBody("this is a test")

mySMTP.Send(myEmail)

Hi, dthayer,

In order to create MailExchangeConnection, we should provide the domain name to resolve the address of the mail exchange server. As following:

Dim myExchange As New MailExchangeConnection("microsoft.com");

...

Thanks

Ok, if that is the case, how am I suppose to test the Mail product before purchasing it, since the evaluation is limited to 11 character domains? That will exclude a lot of them, including ours. I understand that you have to place some limitations on it in order to keep people from abusing the evaluation copy, but why not insert random characters into the subject and or body of the email, or add your "This is an evaluation" message to the subject and/or body instead? Just a suggestion, because I won't be able to actually test the Mail product before buying it if I can't enter more than 11 characters in the domain field.

if you know the host of the mail exchange server, please use another contructor to create the connection class

Dim myExchange as New MailExchangeConnection(new string (){"exchange.microsoft.com"})

our developer will provide you another dll for your demoing later the day.

Thanks

Hi, Dan,

What's your email ? I will send you another version of Aspose.Network for your demoing. Could you send to my email guangzhou #aspose.com?

Thanks very much.
