[imapfilter-devel] enter_idle errors out of pcall

[Lefteris Chatzimparmpas]

Hello,

Currently imapfilter does not try to recover from network problems and
IMAP sessions that have been terminated abruptly.

The pcall() function cannot work in this situation where the connection
is closed in the C part of imapfilter (Lua is just used as an interface
for the C backend).

I don't think you can do much unless you dive into the code, but I will
have a look on how I can improve this situation for the next release...
