[thelist] ASP's Sendmail not working outside our network

[Ken Schaefer]

CDONTS works by creating an appropriately formatted text file and dropping 
it into the configured pickup folder of the MS SMTP server.

You need to look in the MS SMTP server to determine why the message is not 
being delivered. Two common problems;
a) the domain of the From: address is not resolvable in the DNS (eg you make 
up a fake from: domain). MS SMTP server will not deliver these type of 
messages

b) the SMTP server is having DNS resolution problems (eg you have TCP 53 
blocked or similar), in which case it can't work out where to deliver things 
to. Check the /badmail folder for clues on why SMTP Server can't deliver the 
messages.

Cheers
Ken

:
: Yes. I'm not actually sending mail from Outlook (Express). Here's the
: script:
:
: <%@LANGUAGE="VBSCRIPT"%>
: <%
:  ...
:
:  strings = "..."  <!-- Email addresses delimited by ;
:  arrays = split(strings,";")
:  for x = 0 to ubound(arrays)
: Set myCDONTSMail = Server.CreateObject("CDONTS.NewMail")
: myCDONTSMail.From = "myemail at address.com"
: myCDONTSMail.To = arrays(x)
: myCDONTSMail.Subject = "Test Email"
: myCDONTSMail.bodyformat = 0
: myCDONTSMail.mailformat = 0
: myCDONTSMail.Body ="<p>Hey</p>"
: myCDONTSMail.Send
: Set myCDONTSMail  = Nothing
:  next
: %>
:
: ???.. One again, it sends stuff to my at domain.com for example, but not to 
my
: hotmail.com address. I've started logging the SMTP site on IIS, and my sys
: admin is watching the Packets too.

: Until then, if you have any ideas, I'm listening.
