I have an Apache 2.2 web server running on Ubuntu 6.06 LTS. I installed Sendmail using Webmin. Once it was installed, I selected "Send outgoing mail via host:" and I entered my email server, which is on the same network as the web server (public IP addresses for both servers). That is the only thing I changed. The problem is, I am using virtual hosts for 3 different websites, and I need to be able to use sendmail via php for each. Right now, when I send something, it says it came from firstname.lastname@example.org. I need this to come from email@example.com for each virtual host on the server. What do I need to setup for this to work? Thanks!
