[exim] mysql retry times

Afternoon All.

Is it possible to have a mysql query in the retry configuration
so that different domains have various different retry configurations?

something similar to:

begin retry

# Address or Domain              Error           Retries
# -----------------                         -----            -------
*@+mysql_spool_domains       *              ${lookup
mysql{MYSQL_SPOOL_RETRY}}
*                                            *               F,2h,15m;
G,16h,1h,1.5; F,4d,6h

Thanks in advance.

regards

Tom
