Configure Ubuntu 16.04 with LEMP to send emails for multiple websites

I am trying to configure my droplet running Ubuntu 16.04 with LEMP stack to send emails for the websites that I host for things like user registration, order status, etc.

I host several different and unrelated websites on the same server and the problem is that every configuration I have tried limits the that the outbound emails are shown as being from. This is problematic for me as I need the email to be from the domain relative to the website that sent the email.

Perhaps I am not asking the correct question, but I haven’t found anything on how to accomplish this besides set up a complicated and dedicated mail server for the purpose, which is beyond my needs.

Hi @joecasanova

You need to set the From and MAILFROM - you can do that from Nginx or PHP.

In Nginx you would add the following line to you location:

location ~ \.php$ {
  fastcgi_param PHP_VALUE '';
  fastcgi_param PHP_VALUE 'sendmail_path=/usr/sbin/sendmail -t -f -i ';
  ... other lines like fastcgi_pass ...
