We have a mail user on our postfix server that was using the company mail to send compromising information to our competitors.
I've been asked to make a report of the actions for that user in the last time.
There are tools like pflogsumm and others that can extract statistic data, but I haven't so far found anything useful to get all the info for a user because the data is in multiple lines.
I'd like to get something like this:
For the sent mail
11/11/11 00:00:00 email@example.com -> firstname.lastname@example.org 11/11/11 00:00:01 email@example.com -> firstname.lastname@example.org
For the received mail
10/10/11 00:00:00 email@example.com -> firstname.lastname@example.org 10/10/11 00:00:01 email@example.com -> firstname.lastname@example.org
I know I can do a script by myself, but matching the postfix ID for every mail is not something that can be made with a simple grep, and I've a lot of mail history that I have to recheck distributed among different files and so on.
The source log is the standard postfix format, for example this one...
