Recently I rolled out a transition from sendmail to postfix. I've been very happy with the changes except for one feature, which was supported by sendmail but I'm not sure what to do about it in postfix.
This is the use of a backslash before a username in the aliases file. A backslash inhibits further alias expanding. I have found it useful in certain cases to stop mail loops. Is there an equivalent feature supported by postfix? Thanks in advance, j
