Looking for bulk mail allowed servers/hosting providers


I am into mailing and recently started creating my own servers and now I am searching for hosting companies that are bulk mail friendly and won't shut down my servers because of some spam complaints.

I have very good mail list and less bounces too but sometimes due to complaints my server gets taken down.

Anyone in mailing industry care to share?? perhaps you can PM me if you can't post the host name publicly.

thank you!

PS: The email list is not scraped and is valid mail data.
