Bare Linefeeds in SMTP Messages

Bare Linefeeds in SMTP Messages

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.

So the problem is in se_strBody ???  That is, *IT* contains the <br> tags 
but no linefeeds??

Can you just do a 
    Response.Write se_strBody
and then use VIEW==>>SOURCE in your browser to look at what is *actually* in 
there??

It may be that what you really have is
     text text<br>[LF]text text<br>[LF}...
or something similar.

If so, you could simply do
    se_strBody = Replace( se_strBody, vbLF, vbCRLF )

But if you see something else, tell us/show us.

Thanks for your reply, Old Pedant.
The following is what I got according to your suggestion. But I did not find 
any [LF].

RE: Bare Linefeeds in SMTP Messages

Did you ever figure this out?

Sorry, I missed your reply.

The [LF] notation is meant to indicate a Line Feed in the middle of the 
text.  You won't *see* [LF], you'll just see a line break when you view the 
output with (say) Notepad.
