Not sure about hold, but defer means pass a result back to Postfix with the action of defer. Postfix will then respond to the client with a temporary failure code - with the result that the client will back off (defer) and retry delivery later. A good example of this is with greylisting. On initial connection, unless the client-sender-recipient triplet is already whitelisted, the message is deferred. Any RFC compliant server will back off and try again later - eventually succeeding. Most spam software doesn't, and so the spam is blocked. -- Simon Hobson Visit http://www.magpiesnestpublishing.co.uk/ for books by acclaimed author Gladys Hobson.
