Is this so that people won't mark those messages as spam (thus pinning |
| 12 |
the blame on your mail server)? |

If so, let me assure you that it will be ignored. I've even called some |
| 15 |
of our customers with forwarded addresses on the phone and personally |
| 16 |
asked them to stop marking stuff as spam. They still ignore me. |

If this is a filtering gateway, I'm guessing all of your recipients are |
| 23 |
listed in relay_recipient_maps? If so, you should be able to override |
| 24 |
the default_transport (which defaults to smtp:). |

For example, you could set up a disclaimer-only instance of amavis on |
| 27 |
port 10029, and then set the default_transport to |
| 28 |
smtp:[localhost]:10029. I would beware of unintended consequences, |
| 29 |
though. You're liable to stick a disclaimer on some things by accident. |
