I have a contract where the client needs to use 100 of my freelancers for tasks that the client will pay us for completing. The client needs to contact the freelancers via email, which I have set up on my server (userfirstname+ID@mysite.com), I have it set up in PLESK so that all messages sent to these email addresses are forwarded to my email address. However, what about messages sent from this freelancer email address? How can I monitor all messages to and from these email addresses I created on my dedicated server? Any standalone scripts or perhaps settings in PLESK that I don't know of? Your help is appreciated.
