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.
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 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 "whitelist_bounce_relays" lines are also OK.
