[Dmitry A. Kazakov]

The library provides implementations of smart pointers, directed graphs, 
sets, maps, B-trees, stacks, tables, string editing, unbounded arrays, 
expression analyzers, lock-free data structures, synchronization 
primitives (events, race condition free pulse events, arrays of events, 
reentrant mutexes, deadlock-free arrays of mutexes), pseudo-random 
non-repeating numbers, symmetric encoding and decoding, IEEE 754 
representations support, multiple connections server/client designing tools.

Hello Dmitry,

Thanks for providing not so "Simple Components".

AWS provides means to send and receive emails.
Does "Simple Components" provide such facility too ?
I have been through the documentation without finding it.

Do you mean SMTP, POP3, IMAP protocols? No, I didn't implement them. It 
should not be difficult but quite tedious in the part of reading through 
all that huge pile of RFC documents.

I presume with an ability to service multitude of sockets by a single 
task, one could design a nicely horrendous mail bomber in Ada... (:-))

Well, that's not my use case... though I could think about bombing people with "Ada for Automation" related stuff... ;-)

No, sometimes it can be useful to send either an SMS or email when some alarm occurs.

Something like this :
https://www.rosettacode.org/wiki/Send_email#Ada
https://docs.adacore.com/aws-docs/aws/working_with_mails.html

Mister Pascal Obry had one but it seems not available any more :
http://pobry.blogspot.fr/p/ada-contributions.html

It states :
"SMTP		SMTP est une API Ada permettant d'envoyer des messages vers un serveur SMTP."
But the link is dead :
http://pascal.obry.pagesperso-orange.fr/archive/smtp.tar.gz

May be because of integration in AWS.

So, basically, you need only an SMTP client, right?

Indeed a broken link. This should now be fixed. Lot of links where dead
in fact. Thanks for reporting.

Yes, the SMTP component in AWS is based on this one and has evolved and
been fixed since then. Better use AWS at this stage.

The Trash-Finder anti-spam engine (which is 100% Ada code) of course handles 
SMTP in both directions. It wouldn't have been too hard to add POP3 to it 
(never had the need). Whether you consider delivering Ada-Comment mail 
"mail-bombing" depends on your perspective! :-)

The use of Ada makes for highly reliable and maintainable code, which is 
necessary for anti-spam efforts (the code has to be changed periodically to 
deal with new attacks). (And, no, sorry, the code isn't available, as it 
would make it easier for spammers to evade it in a targetted attack -- which 
quite possibly would turn it into an unintentional spam engine via the 
various mailing lists that it filters for.)

If you have a machine learning algorithm in it or a hand-made set of 
rules, disclosing code would show little. It is the trained system state 
that does the job.

Of course, learning as such is inconsistent with reliability, 
maintainability etc, but that is another story.

Yes, that's part of it (the white and black lists obviously do a lot of the 
work), but there is also the issue of precisely how URLs are detected (for 
one example). The less known about that, the better.

I've pretty much concluded that "learning" per-se (that is, automatically 
using characteristics of good and bad mail) doesn't work very well in a 
corporate environment, which the myriad different users have very different 
opinions on what is good and bad mail. For instance, I don't use certain 
social networks, banks, and similar services, so any mail purporting to come 
from them is almost certainly junk of some sort. That set is personal and 
different for any other user of our server (and the filter is intended to be 
server-wide).

In any case, since most of the code is Janus/Ada and Claw-specific, it isn't 
necessarily going to be that useful for someone else. (I still intend to 
port much of it to GNAT on Linux, so it will become more useful when that's 
done -- but who knows when I'll get the time and energy to do it.)

That would be great, especially, if Claw were ported to Linux as well. I 
am honestly fed up with GTK and do not believe Qt is any better.
