Hi, I sometimes send mail through command line interface this way: $ print "short message" | mail -s "your log/pass" test@xxxxxxx The problem is the "From:" address: it is a bit ugly. I would like to set the "From:" address of that system user to be a more esthetic one. I am running Fedora Core 4, and postfix-2.2.2 (Fedora build) I heard about a file named /etc/mailaddress or something like that but I cant find it out on google, or in the archives (I dont remember the exact name). I think in that file I just have to fill it like this: [...] user1 : localpart@xxxxxxx [...] And then it's OK. But i really lost the file name, and dont know if it would be efficient on my Fedora.
