Hello,
We're having a major problem on all of our cPanel servers running PHPSUEXEC with a limit on the number of e-mails a Domain Name can send out per hour.
The limits are set high, 2000 per hour per Domain Name, but the sites we're hosting are considerably large and sending out newsletters. Asking all our clients to limit the number per hour is tiresome.
When the limit is exceeded, the server is completely swamped trying to resend the e-mails only to be greeted with "unroutable mail domain", load shoots up very high (100's) and all other services take a beating. Why is this happening and can be it be prevented? It’s an absolute nightmare, the only to stop it is to suspend the site in question.
