- "marked deleted": IMAP has a "deleted" flag on messages. This
just stamps a message as deleted. It's like putting a label saying
"surplus" on spare furniture in your office: nothing immediately
happens to it other than it being labeled.
- "moved to trash": some mail clients take messages you want to
get rid of out of their original mailbox and move them into a
specially designated "trash" mailbox instead.
Now, mail client behavior:
- Apple's Mail.app and iPhones/iPods: "Deleted" messages are
moved to the trash folder, usually named "Deleted Messages". Any
messages marked deleted in a mailbox are just not displayed.
- Thunderbird: Depending on your settings, one of: a) "deleted"
messages are marked deleted and left in place, b) "deleted" messages
are marked as deleted, a copy of the "deleted" messages is put in the
trash folder, and messages marked deleted are not displayed, or c)
deleted messages are immediately purged.
- IMP (our webmail software): Depending on your settings, one of
a) "deleted" messages are marked deleted and left in place, b)
"deleted" messages are moved to the trash folder, or c) "deleted"
messages are marked deleted, hidden from the display, and a "Virtual
Trash" mailbox shows up that, when clicked, performs a search and
displays all messages marked deleted from all folders that are being
watched for new messages (by default, that's just the inbox). If you
are using the trash but not "virtual trash", messages marked deleted
by some other mail client will be displayed.
- pine (yes, we have a few pine users still): "deleted" messages
are marked deleted and left in place. I believe this is configurable,
but this is the norm.
With all that, you'll end up with some inconsistency. For example,
you can't delete a message in pine and then undelete it from an
iPhone, because an iPhone won't display messages marked deleted.
Choosing the most similar behavior you can in all your clients is
about all you can do. With our webmail software, I kind of like the
virtual trash (enable trash and select "Virtual Trash" in the folder
selection drop-down), with the caveat that messages deleted from some
other clients would end up in separate "Trash" or "Deleted Messages"
