Re: [Imap-protocol] Actually deleting messages from Gmail

I could swear that, in the past,
deleting the All Mail label actually moved the message into the
trash, whereas deleting from any other folder only removed the
label.

In this case, the desired behaviour is to remove the message from
the account completely, not just to shuffle labels. I was more
wondering if I need to actually "move" to the Trash folder (copy,
set \deleted, expunge) or just copy and trust that Gmail does the
rest? It seems like just doing a copy cuts the number of needed
commands to 1/3rd, and yields the same result.

You
can't delete the all mail label from a message in Gmail.
Adding the spam or trash label will hide the message from all
other folders.

If the
all mail folder is the last folder the message is in and you
set your "When a message is marked as deleted and expunged
from the last visible IMAP folder" setting to something other
than the default, it should disappear from the all mail
folder.

As for
what should clients do? That really depends on the client.
If the user (or the app) really wants the message deleted,
then moving it to the trash folder is the right thing to do.
If the user is just trying to remove the message from a
single folder, \deleted & expunge is the right thing.

I was sure that when
I tested previously, deleting a message from "[Gmail]/All
Mail" would cause Gmail to place the message in the Trash,
removing it from all labels, but testing today, this
doesn't seem to be the case, the message reappears without
the \Deleted flag after being expunged:

R00005 SELECT "[Gmail]/All Mail"

<...>

* 1432 FETCH (UID 92405)

* 1433 FETCH (UID 92406)

* 1434 FETCH (UID 92407)

<...>

R0004F UID STORE 92407 +FLAGS (\Deleted)

* 1434 FETCH (FLAGS (\Deleted) UID 92407)

R0004F OK Success

R00050 EXPUNGE

R00050 OK Success

R00051 UID STORE 92405 +FLAGS (\Deleted)

* 1432 FETCH (FLAGS (\Seen \Deleted) UID 92405)

R00051 OK Success

R00052 EXPUNGE

R00052 OK Success

R00054 SELECT "[Gmail]/All Mail"

<...>

* 1434 FETCH (UID 92407)

<...>

* 1432 FETCH (UID 92405 RFC822.SIZE 14202 INTERNALDATE
"21-Mar-2014 03:19:31 +0000" FLAGS (\Seen) BODY[HEADER]
{2044}

<...>

* 1434 FETCH (UID 92407 RFC822.SIZE 14173 INTERNALDATE
"21-Mar-2014 03:55:43 +0000" FLAGS () BODY[HEADER] {2056}

Long-term we're looking at copying messages into the Trash
the way Gmail expects when we actually intend to remove a
message. In this case, is there any advantage in setting
\Deleted or issuing an EXPUNGE, or is it best to simply
copy and let Gmail do the rest?
