A company asked for a solution in one big problem they got. They are a real estate company and ask users to fill out forms if they are interested in a property. But they been having problems with a lot of forms from people that are only joking around and submit non-existant mail adresses. So I saw this idea on a site that sends you an email with an URL with and ID to a CGI that check if the ID is correct and then knows that you really ment to send the form. They really loved the idea since it would take only a couple of minutes for the users to accept the form. So I made the aplication.
I've tested the aplication and It worked great with my accounts I was so happy since I did the script rather fast. I called the owner of the company to tell him that the script was ready and that his webmasters could test it. Suddenly about an hour after I got a call from one of the webmasters telling me that the script takes to long before sending the mail.
So i tested again with other accounts in hotmail, yahoo and my site and they were right...sometimes it took hotmail about 15 minutes to receive the mail.
I have Eudora installed and there is an option when you send email that is called Priority-Mail...I tested and hotmail received the email very fast...so I thought that maybe sendmail had something similar..I've been looking but I can't find how? Could someone tell me how can I do it? Or should I use a perl module?
