Ever since I discovered wildcard addressing in qmail (recipient delimiters in postfix) I have been using them to identify which companies and organizations sell my address. In each case, if I give my email address to foo.com, I send it myaddr-...@domain.dom.
I'd like to have postfix do this checking for me since I've developed a fairly long list of blacklisted recipient addresses now. I want postfix to check the address extension against the domain root and allow or deny accordingly. I know I could do this by writing a script (like greylist.pl) but I was wondering if anyone could identify a built-in solution amongst the many access restrictions and filters provided by postfix. Any ideas? Robert Schmid
