I did that too years ago, but the management of it was kind of annoying. DKIM was just getting introduced when I stopped using it. SPF had controversy. I understand both of those are awesome now.

The biggest issue was if your ip address got listed in a RBL (Realtime Blackhole List), and then nobody would talk to you. Some were easy to get off, others were permanent blocks, and I found those to be constantly interfering with the delivery of mail. At least the rejection would usually tell you which RBL blocked you.

Most RBLs are scams. No competent mail admin uses them to block mail ever.
