I'm running a vps with cPanel/CentOS, And i want to dynamically choose the IP address to send an email from right inside the php code. ( i'm open to any weired ways )
Is there any way to do that? i would really appreciate some clear ideas as i'm not that good at exim and stuffs.
P.S. i already have available IPs in WHM.
Thank you
You can achieve this by using sendmail and passing parameters to define the configuration file to use. Inside the configuration file you can use the Masquerading And Relaying options together with CLIENT_OPTIONS(`Addr=aaa.bbb.ccc.ddd') to send via a certain IP.
When using PHP mail use the additional_parameters to specify the sendmail config file to use and in that config file use the above options to configure it.
