I'm building an auction site in Spring and Postgres where the user can list his product and other user can bid and buy (like ebay).
What I want to do is when some auction ends the system send and email to the user saying to check the page and pay. These dates are stored in the auction table and can be any date (the end date is the starting date + 30 days).
Someone knows how can I send an email on this dates (the best way to do without overload the system!)?
thanks
