# VBounce

This plugin is used to 'rescue' legitimate bounce messages that were generated in response to mail you really *did* send.

## How it works

List the MTA relay hostnames that your outbound mail is delivered through with the `welcomelist_bounce_relays` setting. If a bounce message is found, and it contains one of these hostnames in a 'Received' header in the message body, it will not be marked as a blowback virus-bounce.

The hostnames can be file-glob-style patterns, so `relay*.isp.com` will work. Specifically, `*` and `?` are allowed, but all other metacharacters are not. Regular expressions are not used for security reasons.

## Rules

| Area | Rule name | Description | Default scores |
|---|---|---|---|
| body | `__MY_SERVERS_FOUND` | eval:check\_welcomelist\_bounce\_relays() | -- |
