How can the PHP.ini file be configured to send emails to an SMTP server in the absence of a local MTA on a Linux server?

To configure the PHP.ini file to send emails to an SMTP server without a local MTA on a Linux server, you can use the `php.ini` settings to specify the SMTP server, port, authentication details, and sender email address. This allows PHP to directly connect to the SMTP server and send emails without relying on a local mail transfer agent. 

[mail function]
; For Win32 only.
SMTP = smtp.example.com
smtp_port = 25

; For Win32 only.
sendmail_from = me@example.com

; For Unix only.  You may supply arguments as well (default: "sendmail -t -i").
sendmail_path = /usr/sbin/sendmail -t
