NextCloud 16 review
In May 2019, Linux Journal asked me to write a review and tutorial for NextCloud 16, and so I did. Then they shut down, so I decided to publish it here instead. Please use it!
Dbmail? A great Open Source email system, especially for LAMP/MySql administrators
A couple of weeks ago, I was thinking about how I may build an advanced search utility for my own email archive. One way to make complex queries on the archive seemed to be to put it all into a relational database. Since the Dbmail system stores email in that way, I asked its developers and Harald Reindl (an email administrator at The Lounge who already uses Dbmail: I found him in the PostFix Mailing list archives) if Dbmail could be used in that way.How to reject spam from certain countries (if you must really, really do it)?
Every now and then, a question like this pops up on some email server management forum:
I'd like to be able to reject connections from remote IP addresses if they're from certain countries.The usual reason is either that

Wanted, Virtual Personal Email Servers
(update 2010/05/29: here’s another article about VPES legal, management and economics issues)
The way email is normally used today has several serious limits that I recently explained in another article. I also pointed out that one of the biggest obstacles to personal email management is lack of user demand for Virtual Personal Email Server (VPES) software and hosting packages. A VPES may run into any computer in your home or in some external datacenter, but that is another issue. Here I only want to look at the software side, that is to explain what are, in my opinion, the technical requirements and features of the perfect VPES. You are welcome to add your own in the comments and, if you’re a hosting provider already offering VPES, to add a link to your offer in the same way.

In the meantime, please let me know about anything you find not clear in these pages, so I can improve them, and read this article of mine on how to Build your own email server with Postfix, because it is a good synthesis of the whole picture
