user+detail at domain.com is the envelope recipient reported in the
sendmail log. The entry below doesn't seem to work. The message gets the
default rule applied instead of the 'store notify' rule.
To:     user+detail at domain.com    store notify

I tried both the suggestions below, and they do properly apply the
action "store notify", but for some reason, sendmail then tries to
deliver the message back to 127.0.0.1 instead of the mail hub!
This creates a problem with the same message being scanned, then
redelivered to the incoming sendmail and looping. Other 'store notify'
rules that are defined for normal email addresses work fine.

We forward mail from the MailScanner box to the mailhub using the
virtusertable feature. No other rule or config issue has broken this
before, so I'm not sure what's happening. I'll turn up logging in
sendmail and see if it will tell me what it's doing with this mail.

Any ideas what is going on?
