managing the amount of data that is logged
I was hunting for an email that had the address of a server I work with on it as the origin. However I couldn't find any mention of it in any of the logs. I expect that this is because the email sent out fine (or perhaps was a spoofed IP, thus was never at my server). What I am looking to do though is set the logging function such that every time an email is sent out it writes a line to the log so that I can figure out if the email actually went through my server. I have heard rumor of being able to adjust the amount of logging that happens for various things, though hunting about on the Internet I have come up with nothing.
Any help would be great. Thank you much,
