spam handling rules with +detail email addresses?

[Ken Anderson]

How does MailScanner/SA handle incoming email addressed to
user+detail at domain.com in rules?

Sendmail will strip everything after/including the + sign, and deliver
to the 'user', but rules in MailScanner for both user+detail at domain.com
AND user at domain.com seem to be bypassed when using this syntax in an email.

I've only tested with rules/spam.actions.rules like this:

To:     user+detail at domain.com    store notify
To:     user at domain.com store notify

Both are bypassed and mail gets the default action applied to it if it's
addressed to user+detail at domain.com

Any ideas?

Thanks,
