Hi - it has since emerged that GiP user "d4x" 
employs Microsoft Outlook Express 6.00.2900.5931 
as his e-mail client, which is the built-in e-mail 
client of Windows XP.

"d4x" had recently another Windows XP related 
issue that was posted on the support forum: 
https://squarepenguin.co.uk/forums/thread-686-post-3740.html
and was quickly acted upon by dinkypumpkin, 
but it appears his EOL'd OS is causing him 
extra grief when trying to subscribe/post to this 
very list. 

Registration/Subscription appears successful, 
but no confirmation e-mail is received, nor any 
other list traffic. 

Trying to post directly to the list (in plain-text 
format) results in an immediate bounce by the list. 

I was intrigued by his issue so today I brought 
my WinXP (SP2) desktop out of retirement (been there 
since November 2015) and did some tests: 

When I myself tried to post to the list using MSOE 6.00, 
the test mail instantly bounced back:

I have advised "d4x" to try third party mail clients 
on XP to see if that fixes his issue, have yet to hear 
back. 

I recall some list members are still on XP - can any of 
you replicate reported issue?

Since the deprecation of SHA-1 Hashing Algorithm by 
Microsoft on Jan 1st 2016, I now find many SSL (https) 
URLs simply won't load in XP's IE8, the same goes for 
other functions using OS modules to access the net - I 
believe this is the reason behind d4x's "zeranoe" issue...

To all list members: Please refrain from the obvious 
suggestion d4x should either upgrade to a MS supported 
Windows version or change to an Open Source OS; 
this is not the intent of my post!

To the list maintainer (David Woodhouse): 
Have you purposely blocked traffic originating from 
MSOE 6.00 / WinXP as being an insecure client/OS?

Many thanks for any additional detail/insight on this...

Kind regards, 
Vangelis.
