In Mail 4.2 OS X 10.6.3 MBP 5.3 - I send replies to emails (IMAP) and sometimes they do not appear in my Sent Box. When I click on the View Reply icon at the original received email I get an error that it cannot be found and asking if I have deleted it.
Not *anywhere* to be found. A pain, because not absolutely sure the recipient got it - without asking : ( and have no copy of the reply. Any ideas?
