We run an SMTP server on localhost of all our production Sakai servers and
Sakai delivers all outgoing mail to localhost. The local mail server then
forwards all mail to our central mail servers. This way we control the mail
server to which Sakai is talking and can set setup spooling / retry
/authentication policies for getting mail onto the central mail servers.

I think we are running Exim as our local mail server, just be careful that
you don't setup any local mail server to become an open relay. Our server
just listens on localhost which reduces this risk.
