Im writing a mail form with php and it works fine, kinda. the kinda part is that it dosent always send both emails, the main to me and the auto reply. the auto reply always goes but the one to me is sometimes not sent. It seems to happen more often when i click the submit button a few times in a row. Is it posible that the php file is being run by a new process while the first is still running messing things up? If so does anybody know how to make sure the php file is only accesed by one browser window at a time?
