I've been struggling with Yahoo giving us the  4.7.0 Temporarily Deferred messages on outgoing mail and sticking our mails into their junk filter.   I have one customer who sends responses to a form on their website every night and I want to throttle them for outgoing email to AOL or Yahoo.  I think the amount of connections coming from our server at once is the cause.  Is this possible in SM or with Declude?

An a similar vein, if I enter a value for Max Messages Per Session, what happens if a sender goes over?  Are they delayed or dropped?
