php mail () with multiserver setup

Hi,
I´m using multiserver setup with Debian 6 squeeze according to this guide http://www.howtoforge.com/installin...tabase-servers-on-debian-5.0-with-ispconfig-3

On my web server, I have some Presta shops etc and I need them to send mails via php mail () function.
My mail server is running, what changes do I need to do if I wanna use mail ()?

Reconfigure exim with this guide http://www.howtoforge.com/exim-authenticated-smarthost ?

 

Hi,
you may talk about sender of these emails that is something like [email protected].
Or I've installed SSMTP or you can configure sending emails using SMTP server and user in PrestaShop admin.

Code:

apt-get install ssmtp

With ssmtp package you must to change sendmail_path to

Code:

/usr/sbin/ssmtp -t

And there is a my configuration of /etc/ssmtp/ssmtp.conf

Code:

root=postmaster
hostname={hostname_of_app_server}
mailhub={smtp_server}:25
AuthMethod=LOGIN
AuthUser={smtp_user_name}
AuthPass={smtp_user_pass}
UseSTARTTLS=yes
UseTLS=no

 

thanks for help, sorry for late answer

its working but emails are send from address set in config ([email protected]), any tips how to send them from address which is /for example presta/ running on ([email protected])?
