Hi, I've noted that many of you host your own email and file servers, and I've wanted to do this for several years, but I've been avoiding taking this on myself. This is due to the time investment (to learn tech I don't necessarily want to learn) and the added weight of responsibility for security. Quite frankly, I'm getting lazy in my old age and I'm considering a packaged solution/service like The Helm. I guess my question is, are the tech barriers to setting up a home email server really as formidable as claimed in the below justification from The Helm's web site? If a lazy guy like me sets up an email server, but then doesn't get around to applying security updates for half a year, is he just asking to be hacked? For context, I am a local Charter customer with a standard internet-only subscription. From: https://blog.thehelm.com/post/how-helm-works-part-1-networking [quoted text] For an email server to send and receive email with other servers on the internet, they need port 25 to be open. Unfortunately, ISPs in the U.S. block port 25 by default, a practice started in the 90s when home computers were hacked and turned into open relays abused for spamming. Sometimes it’s possible to get this port unblocked, but it’s not uncommon for the ISP to ask for a significantly more expensive class of service in exchange. ISPs also typically assign dynamic IPs to residential internet connections. Large email service providers block residential dynamic IPs en masse also due to the issue raised above. While it’s possible to get a static IP address from your ISP, they will charge for it and potentially require a more expensive class of service. PTR records, or reverse DNS, is also a key requirement for trustworthiness when setting up an email server. Getting this type of record with a residential internet connection can be a significant challenge and may also incur additional costs. To summarize, port blocking, dynamic IPs and challenges in establishing a PTR record all interfere with easily running an email server at home. It can cost hundreds of dollars per year and consist of a significant investment of time with your ISP to get things set up just right. After thinking about this problem and experimenting for a while, we managed to find a better way. [end quoted text] Thanks, Mike
