| 4 | I wanted to be able to preserve the envelope contents (except for the return | |
| 5 | path when I'm feeling paranoid about error handling). | |
| 6 | ||
| 7 | Feel free to add this to the examples -- someone else might find it useful. I | |
| 8 | also have a complete configuration which I have been recommending to other | |
| 9 | people in Cambridge (although it could work elsewhere with tweaks) at | |
| 10 | http://www-uxsup.csx.cam.ac.uk/~fanf2/conf4.satellite. | |

| 12 | # Deliver a duplicate of some proportion of all messages to a special | |
| 13 | # machine specified in the file /MAIL_TAP_HOST, if it exists. The | |
| 14 | # probability of sending a message is the reciprocal of the second | |
| 15 | # number in the hash part of the condition. The address data is used | |
| 16 | # to prevent redirected addresses from being tapped twice. The | |
| 17 | # originating host and sender are recorded in extra headers. If the | |
| 18 | # delivery fails the bounce goes to a rubbish bin (although this means | |
| 19 | # that the traffic seen by the tap is not quite the same as the | |
| 20 | # traffic seen here). | |
