Hi,

I have a script that sends emails to users, but the emails either get sent to the junk folder or aren't recognised.

If I include the information for referer, sever etc will it make the email more secure and ensure it is delivered?

I know what the server is, but how do I find out the referer, clientip and serverip?

Why are they needed?

PHP Code:

strReferer = request.servervariables("HTTP_REFERER")
strServer = Replace(request.servervariables(""),"www.","")
strClientIP = request.servervariables("REMOTE_ADDR")
strServerIP = request.servervariables("LOCAL_ADDR") 


Thanks,

No. ...

What about including smtp information? I don't know why the emails aren't getting through / or get sent to junk folder.

Any ideas?

Thanks,

There is very little you can do in the email headers to ensure that your mail does not get filtered.
Things such as sending directly to the recipient rather than something like "mailinglist @wherever.com" can help.
Ensuring that the From: name is on the same host the mail is being sent out from
Having a Reply-To: header


One other thing would to see if you can set up SPF (Sender Policy Framework).

Does the IP of the webserver have a MX record associated with it?

Thanks for the suggestions, I managed to get it working by including the smtp host name

Use cdonts component on your windows server so that you can send email easily.

Let me know if you want some samples of it

Might have been 5 or 6 years ago.

CDONTS has been disabled on Windows server for 5 years now

Jumping in rather "after the fact" here, but had a couple observations I thought would still be valuable for folks who stumble upon this later.

@chrishirst is right, CDONTS is mostly out of the picture now as MS ditched it starting with Win2K3 servers (and while you could still get it installed on later servers, why bother?). Frankly, CDONTS ain't great -- though, yeah, @bizcredit, it was easy.

Frankly, CDOSYS is the way to go in my opinion and knowledge of it will be equally valuable to classic ASP programming as to ASP.NET. It's an extremely robust method.

To get back to the original question here, it's best to actually authenticate against an SMTP server before sending out the mail. This will give you a much better chance of not landing your email into a spam folder as the authentication will provide headers that will make the email look a bit less like script generated email.

What's more, any host that allows email to be simply relayed via script is not really keeping there eye on the security issues; that is, perhaps assume that your windows host has an eye on security and doesn't allow relaying and requires authentication. You can never go wrong by authenticating.

I've a nice script detailing just about anyting one might ever want to do with CDOSYS. PM me if you are interested.

Try setting Priority variable to High in your email script.
