It seems (after reading the whitepaper in the above link) to be a matter of
re-sending it in a few minutes (?).
Therefore, is it enough to re-configure the smtp settings so as to retry
several times over a longer period of time ?

You should not need to reconfigure unless you have ytour retry windows set unreasonably short. Moist sites that greylist do so for 3-10 minutes, so if you have reasonable settings, your message will retry in 5 minutes or so and get delivered.

Anyone has experienced this, and knows a workaround ?

I use greylisting on my mailserver.  It is currently the #1 most effective anti-spam measure I have.
