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.
whitelist_bounce_relays hostname [hostname2 ...]
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, "*" 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 "whitelist_bounce_relays" lines
are also OK.
