I had a failure on my main MX server (at a friend's place). A lot of mail got queued. After my friend had repaired his server and wanted to send the mail for me to my courier mailer things went really slow. Courier accepts only very little mail per session. Probably some kind of spam prevention but not wantable at the moment. The mail comes from a known ip (it's my main mx after all ;-)

What I like to know is: what option in which file controls this behaviour? I would like to accept all delayed mail at once next time it happens. Anybody?
