[Mailman-Users] Find a smtp server to send out emails

There are cloud hosting providers that let you send mail directly, although
I can't vouch for the deliverability, since you're typically on a network
full of dusty compromised php scripts.

Digital Ocean and Tektonic have linux VPS images that should be
adequate for modest mailman lists starting at $5/mo.  I'd try Tektonic
since they do a slightly less bad job of managing outgoing spam.
