Hi, i have read your project description, i understand what you want, and i would like to offer you my services. I have excellent knowledge of all required technologies (PHP, various mail servers, and web hosting in general) and lots of experience with them, most importantly including experience with fixing similar issues with email, so i can finish this project without any errors. Feel free to contact me by private message to discuss the details or to get started. I'm looking forward to our cooperation.
