The sender may receive an error if their server has an unusual setup. Such servers must be whitelisted in your greylist software. Of course, there are a number of other errors the sender might get that have nothing to do with greylisting. You really need to see the error before you start trying to fix things. One place to start is search your mail log for errors relating to the sender's email address and/or their server. > > How is greylisting set up in postfix now?

Postfix has no "default" greylist, and there are several that are in widespread use. Look in your "postconf -n" for a check_policy_service entry, then find that service in master.cf. Or some folks use a milter defined in smtpd_milters for greylisting. If you need more help, you'll need to provide "postconf -n" output, master.cf contents, and any associated log entries. http://www.postfix.org/DEBUG_README.html#mail -- Noel Jones
