Tony FinchSome MUAs delete their "drafts" folder when it is empty, so git imap-send should be able to create it if necessary.
This change checks that the folder exists immediately after login and tries to create it if it is missing.
There was some vestigial code to handle a [TRYCREATE] response from the server when an APPEND target is missing. However this code never ran (the create and trycreate flags were never set) and when I tried to make it run I found that the code had already thrown away the contents of the message it was trying to append. --- imap-send.c | 56 +++++++++++++++++++++++++------------------------------- 1 file changed, 25 insertions(+), 31 deletions(-)
