In step 4 for Burirun 1.3-2 testrun Email - POP3 test cases 10907 & 10910 the last line appears unclear and can be interpreted as either:

- "Device-A (FXOS) doesn't have an e-mail, which is moved from 'Inbox' to 'Trash'"
OR
- "Device-A (FXOS) doesn't have an e-mail which is moved from 'Inbox' to 'Trash'"

Passed test cases until wording could be clarified.

As you'll unfortunately find out, POP3 is a terrible protocol, and I think there may be a lot of moztrap cases that were written with the expectation that POP3 can do things that it can't do. This is another one of those cases.

Once you've retrieved the message using a POP3 account, it doesn't matter what happens to it on the IMAP side -- you can delete it, move it, turn it into a pumpkin... POP3 will never see the changes. POP3 merely pulls the e-mail from the server once, and saves it locally to the INBOX. IMAP, on the other hand, stores them on the server and the phone effectively watches the server for changes. Sadly, there's nothing we can do about this.

This moztrap case should be removed, along with any other cases that expect POP3 to do things when an IMAP device changes.

Confirming what Marcus said.  This test case is invalid, per original discussion about POP3 test cases.   Please invalidate the moztrap case (and any others from below in the list).  Excerpting from the thread:

Remove.  If the server supports IMAP, we don't support POP3 on that server.  The user should just use IMAP.  (Also note that POP3 is not capable of doing many of the things that these test cases describe.)
