However, the complexity of Sendmail or Postfix is so daunting, and non-sensical that I have attempted a few times without success. Is there a simple email server that a home user can use, that supports Smarthosting, domain catch-all addresses, and adding users and multiple domains without setting up so much overhead that if you lose it, you pretty much have to start all over.
I don't care about Spam filters, or web-mail, or all that other garbage, GMail does that for me. The infrastructure of these large email systems is too much for a simple home user who wants to enable the power of the web to his/her advantage. eXtremail did it, but no one else has been able to."
