I have a php pipe script that receives an email, takes an attached *.csv from it and parses it.
However, when the email is sent from where it is supposed to be coming from, it silently errors. But when I take that same email and resend it from my address it goes through just fine. is there any simple reason it could be doing this?
try and save some information about the email in a logfile before anything else, then some more info as you parse it. This way you get a more better understanding of what is happening
