| 4 | Hi there, | |
| 5 | ||
| 6 | download the spamassassin package. See | |
| 7 | http://au.spamassassin.org/downloads.html | |
| 8 | ||
| 9 | Define a router in your Exim configuration file. | |
| 10 | For Exim 4 it could look like this: | |
| 11 | ||
| 12 | # Spam Assassin | |
| 13 | spamcheck_router: | |
| 14 | no_verify | |
| 15 | check_local_user | |
| 16 | # When to scan a message : | |
| 17 | # - it isn't already flagged as spam | |
| 18 | # - it isn't already scanned | |
| 19 | # - comes from ABC.DEF.GHI.JKL or MNO.PQR.STU.VWX | |
| 20 | # - .spamcheck exists for this user | |
| 21 | condition = \ | |
| 22 | "${if and { {!def:h_X-Spam-Flag:} \ | |
| 23 | {!eq {$received_protocol}{spam-scanned}} \ | |
| 24 | {or { {eq {$sender_host_address}{ABC.DEF.GHI.JKL}} \ | |
| 25 | {eq {$sender_host_address}{MNO.PQR.STU.VWX}} \ | |
| 26 | }\ | |
| 27 | }\ | |
| 28 | }\ | |
| 29 | {1}{0}\ | |
| 30 | }" | |
| 31 | require_files = $home/.spamcheck | |
| 32 | driver = accept | |
| 33 | transport = spamcheck | |
| 34 | ||
| 35 | ||
| 36 | This router has two advantages (for us): | |
| 37 | ||
| 38 | 1. You can define the sender host addresses from which you will scan the spam. | |
| 39 | In my example there are ABC.DEF.GHI.JKL and MNO.PQR.STU.VWX (you have to | |
| 40 | substiute this by your real IP-Adresses). | |
| 41 | ||
| 42 | 2. The spamcheck router only runs in dependency of the existence of the | |
| 43 | .spamcheck file. So your users can decide whether or not they wont to use | |
| 44 | Spamassassin. Thats important for protection of privacy in germany. | |
| 45 | ||
| 46 | If you don't need this you can simplify the router, for example: | |
| 47 | ||
| 48 | # Spam Assassin | |
| 49 | spamcheck_router: | |
| 50 | no_verify | |
| 51 | check_local_user | |
| 52 | # When to scan a message : | |
| 53 | # - it isn't already flagged as spam | |
| 54 | # - it isn't already scanned | |
| 55 | condition = \ | |
| 56 | "${if and { {!def:h_X-Spam-Flag:} \ | |
| 57 | {!eq {$received_protocol}{spam-scanned}} \ | |
| 58 | }\ | |
| 59 | {1}{0}\ | |
| 60 | }" | |
| 61 | driver = accept | |
| 62 | transport = spamcheck | |
| 63 | ||
| 64 | ||
| 65 | In the end you will need a spamcheck transport. This one works well for us: | |
| 66 | ||
| 67 | # Spam Assassin | |
| 68 | spamcheck: | |
| 69 | driver = pipe | |
| 70 | command = /usr/exim/bin/exim -oMr spam-scanned -bS | |
| 71 | use_bsmtp = true | |
| 72 | transport_filter = /usr/bin/spamc | |
| 73 | home_directory = "/tmp" | |
| 74 | current_directory = "/tmp" | |
| 75 | # must use a privileged user to set $received_protocol on the way | |
| 76 | # back in! | |
| 77 | user = mail | |
| 78 | group = mail | |
| 79 | log_output = true | |
| 80 | return_fail_output = true | |
| 81 | return_path_add = false | |
| 82 | message_prefix = | |
| 83 | message_suffix = | |
| 84 | ||
| 85 | ||
| 86 | Put the router and the transport on the right places in your exim conf and send | |
| 87 | the daemon a HUP signal. Thats all. | |
