Question

我们在经典ASP中使用CDO对象在电子邮件正文中获得随机感叹号（！）标记。

我们没有得到前景的感叹号。问题仅发生在Lotus Notes客户端上。我们使用IIS SMTP服务器发送电子邮件。

修改

Set myMail= Server.CreateObject("CDO.Message")
myMail.Subject="Business and Company News on your Mobile Device"
myMail.From="no-reply@test.com"
myMail.To="some@email.com"
htmlbody = htmlbody (coming runtime)
myMail.BodyPart.ContentTransferEncoding = "quoted-printable"
myMail.HTMLBody = htmlbody
myMail.Send

我认为客户端没有使用SMTP。但他们肯定会使用LotusNotes。

Answer 1

电子邮件中的感叹号通常是由于行太长造成的。将您在ASP中创建的电子邮件正文转储到文件中并进行检查。尝试使用换行符在明智的地方分割线条。我假设这是一条HTML消息 - 在适当的HTML标记之后放置换行符。

Answer 2

我的代码只看到差异

 .HTMLBody= psBody
 .HTMLBodyPart.ContentTransferEncoding = "quoted-printable"

所以HTMLBodyPart....取代BodyPart.....

不知道这是否有所作为，但你可以尝试一下。

Answer 3

如果我没错，“引用可打印”的解决方案可以正常工作，但它会产生二进制附件的问题。所以我编写了一个小的VbScript函数来修复长字符串并使htmlbody与所有客户端兼容。这是：

    Dim string2,pstart,pos0,pos1,part
    string2=""

    do
        part=mid(string1,pstart,76)
        pos0=instr(part,vbcrlf)
        if pos0=0 then
            pos1=instrrev(part," ")
            if pos1=0 then
                string2=string2&part&vbcrlf
                pstart=pstart+76
            else
                string2=string2&left(part,pos1)&vbcrlf
                pstart=pstart+pos1
            end if  
        else
            string2=string2&left(part,pos0)&vbcrlf
            pstart=pstart+pos0
        end if  
    loop while pstart<len(string1)
    fixstring=string2

Answer 4

我找到的最佳解决方案是使用此代码：

ObjMail.HtmlBody="text of your message"
'*** NOTE: the following instruction has to be placed HERE, just after the HtmlBody
ObjMail.HtmlBodyPart.ContentTransferEncoding = "quoted-printable"

它似乎完美无缺！

Answer 5

每行超过750个字符时会发生这种情况。尝试使用vbNewLine或Chr（10）来分割html中的行。

示例：

Set rs = conn.execute(txtsql)

html = ""
html = html & "<h1>Hi " & rs("Engineer_Name") & "</h1>" & vbNewLine
html = html & "<div class=''><table class='maintable'>" & vbNewLine
html = html &   "<thead>"
html = html &       "<tr>"
html = html &           "<th>ID</th>"
html = html &           "<th>Title</th>"
html = html &       "</tr>"
html = html &   "</thead>" & vbNewLine
html = html &   "<tbody>" & vbNewLine

Do Until rs.EOF
    html = html &       "<tr>"
    html = html &           "<td>" & rs("ID_Calendar") & "</td>"
    html = html &           "<td>" & rs("Title") & "</td>"
    html = html &       "</tr>" & vbNewLine
    rs.movenext
Loop

html = html &   "</tbody>" & vbNewLine
html = html & "</table></div>"
