Thank you for your reply. I believe Yahoo does allow for use of php mail. Their online help files provide a generic script (copy and paste this link to review what yahoo has to say about sending php mail: php-17.html)
Unfortunately, this is all that Yahoo provides in the form of a script.
Just so you know, I have already completed Perl/PHP mail setup that they instruct the developer to do. My php email address I have setup with Yahoo is email@example.com. Yahoo also places a limit of 250 emails per day. This limit is not an issue at the current time.
Upon your review of this information, please forward any recommendations, settings, etc. I am really in a bind here. I would like to incorporate the use of Webassist's dreamweaver extensions, including your user registration packet, ecart, and dataassist. It apparent that you utilize UE for all its email function needs. If there is a way to use UE, I sure would like to know to make things more easy.
