Massive Emails for SEO on Dedicated Server

Hi, i use aprox 4k/month email accounts for my SEO, and i need some better solution than hotmail, yahoo, gmail, i need my own server, where i will be able to create massive email accounts, on multiple domains.

I know, but catch-All wont work in my case, i need each email with separated mailbox, there are any services like that? Or any tools to manage that? Automate account creation?

Thanks for your help!

If you use cPanel, you should be able to create a simple script using the API that will create email addresses as you need...
Or you can create a simple bot that automates the task of creating email accounts on your server for you...
