I’ve always found that setting up a mail server on Linux (Postfix, Dovecot, SpamAssassin) is the ultimate "final boss" of self-hosting. One wrong config file and you're blacklisted or open to relay or not able to send any email.

I built Mail Server Builder to bridge the gap between Windows ease-of-use and Linux stability.

How it works:

The app runs on your Windows desktop.\n It connects via SSH to a clean Ubuntu 20.04/22.04 VPS.

It automates the entire stack installation: DNS records (SPF, DKIM, DMARC), SSL certificates, and security hardening.

No CLI knowledge is required for the user.

Why?

To give people a real alternative to $6/user/month subscriptions.

Business Model:

The software is 100% free. It includes an affiliate wizard to help users find VPS providers that don't block port 25 by default, which is the #1 hurdle for beginners.

Would love to hear your feedback on the remote deployment approach or any technical questions!","time":1770899158,"title":"Show HN: Mail Server Builder – Deploy a Full Mail Server on Ubuntu from Windows","type":"story","url":"https://buy-source-code.com/apps/mail-server-builder/"}],[46786196,{"by":"ecto","descendants":172,"id":46786196,"kids":[46792229,46790182,46787546,46787389,46787584,46787383,46792268,46792286,46787778,46786882,46794294,46787176,46787607,46787062,46789497,46787225,46788229,46787408,46787739,46787338,46787529,46792912,46796069,46824060,46792830,46788126,46787063,46794168,46789800,46793606,46796761,46791734,46787198,46787581,46788135],"score":241,"time":1769546174,"title":"Parametric CAD in Rust","type":"story","url":"https://campedersen.com/vcad"}],[46658909,{"by":"saikatsg","descendants":1,"id":46658909,"kids":[46659058,46668089],"score":2,"time":1768664529,"title":"How to Teach People SQL","type":"story","url":"https://dataschool.com/how-to-teach-people-sql/"}],[46591959,{"by":"vinnyglennon","dead":true,"id":46591959,"kids":[46592163,46592188],"score":4,"time":1768240913,"type":"story"}],[46052478,{"by":"terryds","descendants":136,"id":46052478,"kids":[46121827,46121680,46124487,46121883,46121828,46131895,46124374,46123843,46123323,46129554,46128068,46123116,46128257,46121942,46252970,46124682,46131467,46126942,46124102,46124360,46129956,46125525,46123182,46137142,46135526,46124423,46123047,46128680,46129758,46122735,46128649,46136449,46127407,46122766,46129733,46123727,46130051,46126320,46127440,46125198],"score":563,"time":1764115759,"title":"Learning music with Strudel","type":"story","url":"https://terryds.notion.site/Learning-Music-with-Strudel-2ac98431b24180deb890cc7de667ea92"}],[45844419,{"by":"dm319","descendants":113,"id":45844419,"kids":[45888931,45890153,45889765,45844420,45891365,45891560,45890509,45891155,45888858,45892033,45891199,45890637,45888760,45897850,45890483,45890524,45891969,45893845,45890869,45892289,45891457,45889880,45888575,45890812,45844628,45889096,45891168],"score":196,"time":1762502408,"title":"The R47: A new physical RPN calculator","type":"story","url":"https://www.swissmicros.com/product/model-r47"}],[45590949,{"by":"culinary-robot","descendants":101,"id":45590949,"kids":[45596947,45591401,45594493,45592515,45592021,45591898,45595242,45592346,45591201,45636433,45591667,45598756,45592068,45597060,45592556,45591564,45591312,45595438,45591851,45591858,45597948,45596788,45592061,45602339,45596970,45605864,45594135,45595459,45595621,45603433,45599542,45593321,45595428,45600882,45599703,45597150,45595295],"score":381,"text":"I started working on Halloy back in 2022, with the goal of giving something back to the community I’ve been a part of for the past two decades.
