Sending email / question on spamming

[puzzolino]

This is not strictly a VC++ issue, anyway I'm facing this problem in one of my VC++ projects, so please help me.

My program sends emails using IIS SMTP service on Windows 2000 Server.
Users with an account on hotmail or yahoo get the email on their spam box, which is something they're no used to.

Most users simply give up, others ask about it, very few find the email in the spam box.
How can I make my emails come in the correct folder?

Thanks in advance.

Are you writing legitimate email or SPAM?

You can't. You'll have to look into why you're emails are getting flagged by Yahoo or Hotmail as spam.

It can be a number of things. I suggest you setup a hotmail or yahoo email account and send an email to yourself, then start fishing through the headers. Or you can always inquire directly to MSN and/or Yahoo and see what they think.

It could be your domain, it could be the reverse lookup, it could be your IP address the email is coming from, or any number of other things...

Otherwise, tell your users, and let them whitelist your sending address so they'll always get your emails in your in-box.

I agree with slanted on this being the problem. I'll bet they are doing a reverse lookup of your IP address and not finding a MX record for that IP address and defaulting it to suspected SPAM.
