Hello Steffen,
I'm sorry to report that the problem has not gone away entirely. I
appear to get two kinds of error conditions. As I last reported
I've had the error message
s-nail: TLS socket read error, retrying: Resource temporarily unavailable
s-nail: IMAP: error:00000000:lib(0):func(0):reason(0)
while in the editor, and when I saved and quit, the edited version DID
appear in the message.
That seems to happen when I lose my connection to the internet
altogether, not just to the IMAP server, and the error message comes up
in the s-nail window while I am still in the editor.
In the other condition, the message
s-nail: IMAP write error: error:00000000:lib(0):func(0):reason(0)
appears only when I leave the editor, and I don't know what event causes
it. That's the circumstance in which the editor temporary file doesn't
get read back into the message buffer, and the temporary file remains in
place until the message is sent or abandoned, at which point it is
deleted.
What chain of events can lead to an IMAP write error?
Stephen Isard
