Kevin,

It's been our experience that hosting your own email server on a consumer ISP is a nightmare. Because of the spam and bots many companies (mine included) simply drop mail from anything that remotely resolves to a consumer ISP IP. There are solutions around this. Amazon has a service (SES) that can front your mail server and will host your MX records. You'll still need to handle a tremendous amount of spam filtering, etc.

When you say FTP server I presume you mean SFTP?

As for a NAS, you might be interested in something like FreeNAS Scale. It's linux based, it'll run on anything. It handles the whole ZFS setup and configuration of services, etc. It also very clearly supports docker and has a nice interface for installing applications. So you can very easily install something like Min.io and now your NAS has S3 bucket capabilities.

For security, you might want to think about setting up something like tailscale so you won't have to knock (too many) holes in your firewall to handle the incoming traffic devices and the NAS will be on a private WAN.

I am looking for a cheap solution for the following:

1) Email server/redireector. I want to have a full custom domain and
email addre0ss.

2) FTP server on the same domain as the email server.

3) GUI setup preferred, I do not want to invest the time (right now) to
get this working as a 'ground up'

project.

4) Total bandwidth needs should be negligible.

How would you approach this?

At a very high level, I am considering:

1) Dedicating a DDR3 (RAM) era Intel I3 P.C. (sorry, I don not know the
generation) and installing NAS software with the appropriate docker
plugins, if they exist. I do not know if this is even reasonable.
Suggestions are appreciated. I am using a home ISP account. I am aware
of DynDNS type services to get around the lack of a static IP. I do not
currently plan on using this device as an actual NAS due to security
concerns. If necessary, I will use sneaker-net to transfer data,
although I am thinking about ssh or even RS232.

2) Renting out space on a service like Amazon Web services. Maybe they
have an image that is already what I want.

Any ideas/thoughts/experiences would be appreciated. I hope to be at
the meeting next Thursday.
