I don't know, but befor my user send 50k mail/day, the mail server is work, and after that, mail don't work. I reinstall exim, but the problem no change.
I use this comand to del all mail spam
If the user sent 50,000 emails the server may have ended up on blacklists. If the server IP# is on blacklists, many other mailservers may be refusing to accept mail form yours.
Check your main server ip# here (mxtoolbox.com) to see if your server is on any blacklists.
