#20512 — Whatever happened to the 'Cancel Message' option?

I have the latest TB (140.10.2esr (64-bit) ) on my desktop. I use it
both for emails and usenet access.

I don't know when, but somewhere along the line TB has lost the 'Cancel
Message' option. This was useful when a message was sent twice, for
whatever reason.

[I realise not all mail servers accepted the 'Cancel' command, but at
least the option was there for those that did. ]

For usenet, it is possible to cancel a message. Thunderbird checks if it 
is your message (most likely by the mail of the author), if not, the 
option is not available in the Message menu.

Post a test message to misc.test and then use Message (menu bar) --> Cancel

I would not have posted this message if Message (menu bar) -- > Cancel
was there. It is not.

Is that a message that you posted with the mail address used in your 
newsgroup account?

For TB 149.0.2, I can see this option - but only for "my" messages.

For TB 140.11.0esr (64-bit) I cannot see that any more. (It used to be
an option.)

I have it here on BB 140.11.0esr on Windows and TB 140.11.0esr on Linux.

Post a new message to misc.test - then try to cancel it.
Does this work?

Well... blow me! 'Cancel' worked.

Now I'm baffled. The option (in TB) sometimes it's there, sometimes not.

When you send a msg, it 'quickly' propagates everywhere. Some NSPs 
facilitate a cancel-lock and cancel-key system. If your NSP does, then 
it will accept a cancel for your own msg on your own server ONLY.

Basically no one accepts 'ordinary' propagated cancel msg/s because of 
the potential for abuse.

A sort of 'bottom line' is that for the most part, cancel does not work. 
I don't know what Tb did w/ such a function.

Gmail's webmail function 'pauses' the sending of email a very few 
seconds so that it is possible to halt the Send function if one is quick 
enough.

Turnpike has a delay after you've "sent" (both emails and posts) - about
a minute IIRR, can't remember if it was adjustable. Very useful! (And
could be overridden if you really wanted something to go this instant.)

Could be useful for TB (and others)!

Since there are different kinds of humans, there are different kinds of 
'human natures'. For some people, the 'mental confirmation' of send 
comes BEFORE they hit send; for some other people, they might tend to 
have 'second thoughts' AFTER they 'overly hastily' send something 
'rashly'.  That is, some people do things rashly like email content, and 
some people don't ever do anything like that; so they don't need any 
kind of delay after the send button.

In my case [OP] it is invariably a case of  malfunctioning of TB and /
or my USENET provider.  Very often, I 'send' my message. TB is seen to
be 'Assembling the message', but then nothing happens, or there is a
message saying the 'Message could not be sent'.

Fortunately this is not a consistent behaviour. After a second or third
attempt, it is eventually 'sent'. Alas, sometimes the subsequent 'send'
works and it appears alongside the original - which may have arrived
with some delay.

I'm familiar w/ a form of that.

In the relationship between Tb and my NSP, during a type of inactivity, 
Tb 'times out', as it doesn't keep the transaction process w/ the NSP 
alive.  That timing out may or may not be accompanied by a notification.

In any case, when I've been inactive, I use the little icon in the 
status bar for online/offline, and click to go offline, then again 
online. This 'refreshes' my transactional status w/ the NSP.

If I don't do that, and Tb/NSP have 'lost contact' then the sending of a 
msg results in a 'assembling message' condition that is NOT sending; 
whereas the refreshing brings about a 'connecting with' condition and 
sending is successful.

However, in my case as described above, the problem and its resolution 
are NOT 'opaque' but transparent; I can tell what is going on when a 
message isn't getting sent properly, 'tho' I can't always tell when the 
contact is being lost.

I /can/ tell when a message isn't being sent; I can't always tell when 
the timing out actually occurs.

OK, but this is just as much an annoyance/inconvenience  as resending
the original message again. (To be honest, it is a bug which has become
a feature for me. I take the opportunity to re-read my unsent message
and correct any typos or foot-in-mouth statements.)

NOT answering the question:

You do NOT wanna cancel a message that's been sent/leaked. So make sure 
that you don't need to use it. :)

I always use the 'Send Later' feature so that I have time to think about 
what I'm writing and who I'm insulting!

I never send emails immediately; they always sit in the outbox for 15 
minutes before I manually right-click to send them.

It's always a good idea to pause and gather your thoughts before losing 
your temper with someone.

Trump should do the same before writing rubbish on his 'Truth' platform! 
His writings has made this world a very dangerous place for everybody.

The accidental re-sending of an email may not have anything to do with
ill thought out emails.

In my case, I have noticed that emails I send via TB sometimes do not
get sent, or at least do not appear on the usenet newsgroup. In this
case I resend, only to discover that now there are two identical copies.

Emails aren't supposed to appear on news groups. Newsgroups contain news
articles. Perhaps you could clarify whether you are talking about News
or Email?

I am talking about messages sent to usenet newsgroups e.g.
alt.comp.software.thunderbird

Hit the F5 button next time after posting in a newsgroup, for refreshing 
the newsgroup's view.
