I was assuming you look for hard fails of outgoing mail (the ** lines in the exim main log) I suppose this will miss mails that get soft failed at the receiving site ( the == log lines ) and there are a few sites that respond to spam/virus with 4xx. | At Demon there's a transfer onto a fallback system (so as to keep the | main machine queue sizes under control) and that gives a suitable | breakpoint for declaring a "failure" without a great deal of book- | keeping in the log processing programs Sorry - I'm lost now. Many outgoing spam/virus mails will fail immediately, wheras some legit mails are delayed for one reason or another. So I don't quite see how the fallback hosts system helps here. Surely you need to track each message-id submitted (<=) and wait to see which end up failing (**). -- ## List details at http://www.exim.org/mailman/listinfo/exim-users ## Exim details at http://www.exim.org/ ## Please use the Wiki with this list - http://www.exim.org/eximwiki/
