Postfix main.cf configuration
New here and just a general newbie.
I have a fasthots server running Centos. I was recently trying to get the php mail() function to work, and started editing my main.cf file in etc/postfix/.
A file called main.cf.bak existed and I assumed that it would be exactly that. Upon editing my main.cf and rebooting, Postfix will not start and I have a load of angry customers wanting to use their email.
I can't for the life of me get it going again. I have even followed the tutorials here. I think my lack of knowledge has let me down.
Does anyone have that original main.cf that fasthosts use on a centos deployment??
Is anyone a wizard that could help?
