Webmaster Forum / ASP / Components / June 2008

I don't know if this is the right forum. I was trying to send out email using
CDO.Message. (Windows 2003 Server with IIS 6) But some of our clients could
not receive our emails. I checked the SMTP server log, and found that
   "OutboundConnectionResponse SMTPSVC1 S79349 - 25 - -
451+See+http://pobox.com/~djb/docs/smtplf.html. 0 0 47 0 593 SMTP - - - -"

Then I did some search and found the following articles
   1) Bare LFs in SMTP (http://cr.yp.to/docs/smtplf.html);
   2) Bare Linefeeds in SMTP Messages Cause "The Connection Was Dropped By
The Remote Host" Errors When Using Microsoft IIS 6 SMTP Service
(http://www.dylanbeattie.net/docs/iis6_bare_linefeed.html)

It seems that explains my problem. The solution is replacing "\n" to "\r\n".
However, my problem is, I use HTML format to compose mail body, and there are
"<br>"s instead of "\n"s. And the mail is sent by the following code

...
Set iBp1 = iBps.AddBodyPart  ' Add a BodyPart object to the hierarchy
Set iBp2 = iBp1.AddBodyPart
With iBp2.Fields
    .Item("urn:schemas:mailheader:content-type")              = "text/html"
    .Item("urn:schemas:mailheader:content-transfer-encoding") =
"quoted-printable"
    .Item("urn:schemas:mailheader:expires")                   = datExpiry
    .Update
End With
Set Stm = iBp2.GetDecodedContentStream
Stm.WriteText se_strBody
Stm.Flush
...

How can I solve the problem? Thanks.
