loadplugin Mail::SpamAssassin::Plugin::VBounce [/path/to/VBounce.pm]
The following options can be used in both site-wide (
user_prefs) configuration files to customize how
SpamAssassin handles incoming email messages.
The hostnames can be file-glob-style patterns, so
relay*.isp.com will work.
? 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
whitelist_bounce_relays lines are also OK.
