# Mail::SpamAssassin::Plugin::VBounce(3pm)

aid in rescuing genuine bounces

## NAME

Mail::SpamAssassin::Plugin::VBounce - aid in rescuing genuine bounces

## SYNOPSIS

```
 loadplugin Mail::SpamAssassin::Plugin::VBounce [/path/to/VBounce.pm]
```

## USER PREFERENCES

The following options can be used in both site-wide (`"local.cf"`) and user-specific (`"user_prefs"`) configuration files to customize how SpamAssassin handles incoming email messages.

- welcomelist\_bounce\_relays hostname \[hostname2 ...\]

  Previously whitelist\_bounce\_relays which will work interchangeably until 4.1.

  This is used to 'rescue' legitimate bounce messages that were generated in response to mail you really \*did\* send. List the MTA relay hostnames that your outbound mail is delivered through. If a bounce message is found, and it contains one of these hostnames in a 'Received' header found the 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.

  Multiple addresses per line, separated by spaces, is OK.  Multiple `"welcomelist_bounce_relays"` lines are also OK.
