TCP connections are reliable.  Run, don't walk, to your nearest technical
bookstore and read about network layering.


TCP connections are more reliable than UDP; that does not mean they are 
reliable, full stop.


I agree that most ugly, stupid software too quickly resorts to dumping a 
connection. But it sounds like you're just arguing the other, equally 
wrong, extreme. Software that doesn't take into account that TCP 
connections often do either fail completely or stall for so long as to 
constitute a failure to, you know, a normal person who's trying to get 
something done interactively, is just wrong. Patience is usually but not 
always a virtue.

Was that what you said, or was it not? It quite clearly was, so the retort 
was typically nothing (particularly indicative of a generation to which I 
do not belong).



The righteous thing is to follow the specifications; and if you think that
the specifications are incorrect then work to get them changed.  You're
the one who seems to be angrily insisting that the specifications
shouldn't be followed.


Oh? I'd be quite curious for you to teach me where it was that I said such.


And then to make stupid statements such as TCP is not reliable.


Or stupid statements such as, You're talking about failures at the 
application layer, but you shouldn't try to address it in the application?



Pshaw.  So you want to bring up Linux's half-duplex close behavior, eh?


You may project anything you wish...


That's irrelevant to RST in IMAP sessions.


... so that you may be comfortable in refuting it.

By calling something Trash, you are inviting its destruction without
notice to you.

Trash.  n.  things that you throw away because you no longer want or need
them.


Quote the dictionary all you want; while I agree with you in an ideal 
world, people have been conditioned by 25 years of GUI metaphors that say 
otherwise, which is why the purist recommendations are broken. Pure and 
simple. You might think those GUI metaphors are bad (and I would be right 
there agreeing with you), but our opinion is irrelevant.


Some of the other assertions in this discussion are counter to what I've 
seen and studied in users and analysis of their mail usage, but it's all 
just about as irrelevant as what Merriam and Webster have to say about 
Trash.

Look at the above very carefully.

imapd says that Trash/test/ is not subscribed.

The .mailboxlist file shows that Trash/test is subscribed.

Note the difference in the two strings.


Just to be explicit, the moral of the story is that using subscriptions is 
not a good idea because every client is stupid in their handling of subs, 
and worse, they're all stupid in slightly different ways.
