[Design] Feature request: A "no, wait!" capability

[Ray Ryan]

Okay, I expect this will get shot down, but I'll share it in the spirit 
of brain storming.

Back in the days of UUCP dial up, when I found that I had hit the Send 
button at the wrong time, I had a bit of time before the mail was going 
to leave my box. Call it the, "oh, SHIT" interval. I could whip up a 
command line, nuke the appropriate spool file, and wait for my pulse to 
subside. This ability saved me a great deal of embarrassment, and I 
miss it.

In the modern always-on DSL or better environment, you hit the send 
button on a short note (or type the Send key-sequence by accident), and 
often in less than a second it's out of reach.

I've long wished that my mail clients had a built in sanity period, say 
a sixty second timer per note that would keep them in my Outgoing box 
before actually bothering to send them. Nothing in your face, no "Are 
you sure you want to send this?" dialog, the Compose window certainly 
should not stay visible until it actually goes. I just long for a place 
that I can go and nuke a premature email emission before it does me any 
harm.
