I am building an application to send mails to a list of users, provided by a client. The client's server does not support PHP so I am offering my server. But as there is a danger of spamming from the client, I do not want to use my smtp mail server, but client's smtp server. Is there a way that PHP pages are on my server, and when the mail is sent, it uses some other smtp server and not the one that is provided by the hosting company. I know this is possible in ASP with CDONTS or any other component, but is it possible here too? Thanks in advance, JetPatcher.
