Characters appearing in email sent via SMTP

Hi,

I've written an application for my company that will send an automated email when a certain condition has been met. The text for these emails originates from a text file. When the email has been sent and arrives in a users mail box, an exclamation mark appears at approximately character 990.

I've done a test just sending the characters 1234567890 and its nothing to do with the text file, and I've played with bodyencoding and bodyformat to no avail. Any ideas?

       With CfH_Message
            .From = From
            .To = To
            .Subject = Subject
            .Body = Message
            .BodyFormat = MailFormat.Html
            .BodyEncoding = System.Text.Encoding.Default
        End With
        SmtpMail.SmtpServer = ConfigurationSettings.AppSettings("SMTPServerAddress")
        SmtpMail.Send(CfH_Message)


using the 1234567890 the results are as below (note the ! towards the end). The ! does NOT appear in the text email message. The proper text is in the form of a Dear Jo Bloggs email to a user, who happened to notice the exclamation mark towards the end of the email amongst various words (depending on the email). How has it appeared? This has been added AFTER the smtpmail.send. How can it be cured?

Try this:
.BodyEncoding = MailFormat.Base64

MailFormat.Base64 does not appear as an option - only .HTML and .TEXT appear.

btw I'm using ASP.NET v1.1

MailEncoding.Base64 exists but setting .BodyEncoding to this results in
"Value of type 'System.Web.Mail.MailEncoding' cannot be converted to 'System.Text.Encoding"

I'm using Imports System.Web.Mail, allowing me to do  Dim Cfh_Message As New MailMessage

examples that I've seen on the net that use MailEncoding.Base64 appear to use System.Web.Util, but if I use this I cannot create a mail object as above!!! (Type MailMessage is not defined). Grrrrr

There's a strange bug where if you have a string of length 512 or more without a line break random exclamation points appear in the email body. Add some code to insert a line break every 400-500 characters.

I discovered a similar idea - see http://www.systemwebmail.com/faq/4.4.5.aspx - need to do a vbcrlf after every paragraph - I've applied a patch and it appears to work!! :-)
