51 | ## If we're verifying an address and the recipient has a `~/.mail/spam-limit' | |
52 | ## file, then look up the recipient and sender addresses to find a plausible | |
53 | ## limit and insert it into the `address_data' where the RCPT ACL can find | |
54 | ## it. This router always declines, so it doesn't affect the overall outcome | |
55 | ## of the verification. | |

57 | ## As a result of forwarding and aliasing, the original envelope recipient | |
58 | ## may have been set a while ago, so we'll search through the history until | |
