Re: MailChimp--I learned about the site by searching old threads, but unfortunately it doesn't seem to fit my needs to allow the group to send messages among each other.
Yes, MailChimp is optimized for sending the same message to a large number of people at the same time. It's not good for sending email ad-hoc one at a time.
But MailChimp has a subsidiary, called Mandrill, which offers exactly the kind of service that MailChimp doesn't. I don't know why they don't just offer all the services under the same brand, but it's their company, not mine
Even if you run a mailing list software on your own server, it's often a good idea to outsource the actual sending (SMTP and all of that) to a third party such as Mandrill, because their servers will have an easier time getting through spam filters.
