I setup centos5 perfect. I have a dynamic IP and am using noip dot com. I have a php dating script I want to install. the script installs on the database with mail accounts set up. It has auto reply when someone signed up on the site. Will this program run on my server and if it will, will it be able to send emails to peoples hotmail and yahoo accounts for registration to the site? Or do I need to get a static IP for mail to work corect ?
The script will run on your server, but the emails will not be received by hotmail or yahoo accounts. Yes. Either you need a static IP address or you must relay your emails trough a mailserver with a static IP address.
script install There is a place in the setup of the script to enter a email address and a smtp string. Can I use my ISP smtp string in the program and a email from my ips providers emails server ? and if so do I need to configure anything else for it to work ? This way the mail will work correct and I can hold off on getting the static ip for now.
Yes, but you will need a username and password for that server as well. But you could as well make your own server relay emails through your ISP's server: http://www.howtoforge.com/postfix_relaying_through_another_mailserver
