[Alpine-info] Can't postpone after lost connection

[Benjamin R. Haskell]

When I'm on a flaky wireless connection, I often get disconnected after a 
long wait (end result: "Folder INBOX closed due to access error") while 
composing mail. Once that happens, I'm stuck. I can't postpone the 
message, since the postponed-msgs folder's on the same server. Nor can I 
send it, since I Fcc that INBOX.

After the network connection is restored, trying to postpone, I get:

[>Fcc Error: "Folder exists.". Message NOT sent or copied.<]

and if I try to send, I get:

[Fcc creation error. Message NOT sent or copied.]

I end up invoking the alternate editor to save the file, and resend. But, 
it happens pretty frequently at certain places where I use my PC, so it'd 
be nice if it did something "smarter". (reconnect as needed or similar)

Best,
Ben
