I changed hosting provider, but new provider doesn`t support send e-mails use php.

What need install on server to send e-mails use php?

IPs can’t help you install stuff on your server. That’s outside their realm of support. However if you can’t use php mail, IpB supports sending mail via SMTP or via some third party companies like Sendgrid.
