Mail::SpamAssassin::Plugin::VBounce - aid in rescuing genuine bounces
loadplugin Mail::SpamAssassin::Plugin::VBounce [/path/to/VBounce.pm]
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.
This is used to 'rescue' legitimate bounce messages that were generated in response to mail you really *did* send. List the MTA relays that your outbound mail is delivered through. If a bounce message is found, and it contains one of these hostnames in a 'Received' header, 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,
? 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.
