I use to have three Gmail accounts (notifications, mailing lists and personal). After the 2012 domestic spying revelations, I deleted all of them, extracted all my Gmail and hosted my own. It's so much nicer than dealing with Google's fucking terribly broken IMAP interface and over aggressive spam filter (which has bitten me too):

..although e-mail delivery has seemed to be getting better in the past year.
My current Google account has no g-mail connected to it, which has lead to some interested bugs in Hangouts (you can't search for Google contacts once G+ went away, even if you clearly see them in current chats).
I also host my own Calendar/Contacts using Radicale + DavX (formerly DavDroid)
