Ideal corporate email client

When it becomes necessary to set up a mail system for a company, first of all it comes to mind to use solutions from Microsoft - Exchange and Outlook. Unfortunately, these solutions do not provide sufficient flexibility and many do not fit in different parameters.

Well, but what to use instead of them, because you want the same beautiful and transparent for the user to work with mail, which provides the MAPI protocol? A small shuffle and the light gives rise to a completely obvious and in fact no alternative solution - IMAP . IMAP, thank God, in the modern world almost all email clients support one or another degree, so our choice is huge. But if you take a closer look, it narrows to a very modest set of one or two titles.

So, we would like to:

To begin with - cross-platform. It is foolish to use standardized technologies, but initially being tied to one OS, then it’s easier to buy Exchange right away and forget about any flexibility of the deployed infrastructure.
Full support for IMAP and IMAP ACL . The second point is important because without it, it will be impossible to organize neither shared folders, nor the transfer of rights to various operations with the box to other users, and without this in the corporate mail system in any way.
The ability to centrally configure the client through the server.
Client configuration flexibility and ease of use.

A brief search on the Internet can tell that the only option that could be considered closer is Mozilla Thunderbird . But the question is: can Thunderbird provide all the necessary functionality so that you can easily replace Exchange and Outlook with it? It turns out not only can, but also allows you to achieve much more than just a banal imitation of Microsoft products.

To begin with, of course, you need to decide on the server, but something I was too smartly going to replace the entire infrastructure with the mail client. I use Dovecot because it is one of the most reliable and flexible products in its field, but most importantly, Dovecot is the only widely used server that fully implements IMAP support . You can use any other server, but for maximum efficiency, your server should at least support IMAP ACL.

In the wilds of configs

Now let's go directly to Thunderbird. All settings Thunderbird stores in the form of many favorite text-based configuration files, but in a somewhat unusual manner. Thunderbird configs are JavaScript scripts. And Thunderbird does not just read them, but executes them. A very funny conclusion follows from this: one can use many possibilities of JS to dynamically generate the necessary parameters. Of course, JS support in Thunderbird is far from complete, but we will have enough of it with interest.

The main Thunderbird configuration file is stored in the user profile and is called prefs.js . Just in case: the Thunderbird profile is located either in the home folder (for Linux), or in AppData (for Windows), or in the program folder (for Thunderbird Portable).

The format of the specified file is quite simple, it consists entirely of lines of the form

user_pref("app.update.auto", false);
