Limiting Spool or Queuing Size

So this week I noticed that the spool directory was filling up the entire storage for me VPS over 125 GBs. We have a huge mailing list, but I was wondering what people did to manage this? I didn’t see anything where you could define the spooling size or queuing threshold, and it appears that Mautic wants to generate all the emails and then send them per the queuing parameters. I was considering making a virtual hard disk volume and overlaying this on the spool directory so it would be limited to say 25GB without crashing the whole server. Or doing the same for the entire mautic_data directory. Anyone have any thoughts on this?

No not yet but you can hire a programmer to do it except you are one
do a backup first because try it so if anything happens you can restore
