If a server is down, then the retry algorithm applies, and the
time between retries increases the longer it is down. It can
get quite long.
What you're seeing is probably not that mail "does not get sent",
but instead that it "does not get retried soon enough".
When a retry succeeds (e.g. your forced retry), the retry
time/gap for that host is reset (i.e. the algorithm starts
again), so things get delivered in a more timely fashion.

You can force that domain to have a better retry algorithm. Or
you can setup the intermittent host to request a retry from the
relaying server - using the "ETRN" mechanism - both servers need
to be configured for this to work.
These two solutions are well documented.
