Is there a way to limit this time or the number of attempts?
what if ?, you should not maintain remote problem resolving, since its not your postfix that have problems
but if you really like to test, you can change queue lifetime from default 5d, if you run a well configured backup mx then it could be extended not more limited, and then use failback relay on the non backup mta
so first attempt wold be normal try, but in case of fails it would be moved to your own backup mx with longer time on redeliver try and queue life time
