[exim] Number of retry rules

Hi all,

On some of my large relay servers we have problems with destination
servers greylisting our server for 5 minutes, but by default we don't
retry for 15 minutes, so is it possible to list more than 3 retry
parameters in a rule?

For instance I'm thinking of doing something like this:

*    rcpt_4xx    F,15m,3m; F,2h,15m; G,16h,2h,2; F,6d,8h
*    *        F,2h,15m; G,16h,2h,2; F,6d,8h

Is the first rule going to work ok with 4 retry parameters?

What do other people use?


Thanks,
