Sending Mail to Hotmail Users?
Cafesolo wonders: "I'm developing a web application using PHP. It has a user registration system that sends a link via email to activate new accounts. I've found that sending mails to Hotmail accounts is very difficult, because the spam filter is very strong and it filters lots of non-junk messages. I think the spam filter blocks any email whose domain isn't in an internal whitelist (which might contain popular domains, like hotmail.com itself, gmail.com, yahoo.com, msn.com, etc). Most of my users have Hotmail emails. I can't simply tell my users to read the junk folder because most of them are not computer-savvy and that seems to be a bit confusing to them. Has anyone managed to solve this problem? Did somebody try to contact Microsoft? Is there any way to get whitelisted? Can an independent programmer get his domain whitelisted?"
Also, have you tried sending the email spoofing the receivers email address?
Never do this. Forging the return address is one of the few things that actually is illegal.
Moderating "-1, Disagree" is simple censorship. Have the guts to post your opinion.
Welcome to my world. I work on email deliverability for a financial services company, so no, I'm not a spammer. Hotmail makes two tools available to you to help you get your email delivered:
MSN Smart Network Data Services: http://postmaster.msn.com/snds/
This will let you put in your SMTP's IP address and it will give you consolidated stats on how much mail was received, and how much was filtered as spam.
Sender Score Certified: http://www.senderscorecertified.com/
This company will "certify" you as a safe sender, and Hotmail will let your emails in unfiltered. The catch is you have to pay for this.
Good luck. It isn't easy, but at least there are some tools at your use.
