If you're asking me, I wouldn't mess with freeradius.

Maybe the better idea is to create a small cron script which can read the database and send email according to the date and the time diff you want (1, 2, 3 etc days before the expiration)

Hi,

    I am looking for how to send email before expiration of account. The value used for the expiration in radius is character format. So, I would like to know how to compare the expiration data and send email accordingly.

Thanks in advance.

John.
