Disconnected from IMAP?

Disconnected from IMAP?

[Aaron Hsu]

Hey All,

When using Gnus, it seems that for some reason, after a period of time I
am disconnected from my IMAP server (newsservers do not seem affected by
this). Now, when it tries to reconnect (on a STARTTLS connection), it
says that it can't connect, and then it refuses to do anything with this
server. I see this when I am writing a long email and I just happen to
run into trouble there, or if I leave Gnus open for a while and then try
to get new messages. Running a restart seems to fix the problem, with by
an explicit quit and then M-x gnus or by issuing the `R' key.

Does anyone know what this is an how to fix it?

The server you are connecting to might be automatically logging you
out after a certain period of idle time.

That shouldn't happen. What does the server buffer say when it does?
Denied?

That shouldn't be necessary. In the server buffer hit 'C' to close the
server and then 'O' to reopen it.

Yes, it says denied.

This is a handy workaround, thank you for pointing this one out to me. I
would still like to find a way to not have to do this, because that may
mean swtichout out of my editing session in the middle of something and
restablishing the connection before going back in to make sure
everything goes where it should.

Very strange. What does fstat say about the emacs process when the
problem happens? Does emacs still think it has a TCP stream open to
your IMAP server?

Are you using some kind of network address translation between you
and the IMAP server that might be expiring when the connection has
been idle? Or perhaps just a firewall of some kind?

I am using a rather extensive set of routers, and it does happen that
the connections are terminated by the routers at times. However, I would
then expect Gnus to be ``disconnected'' and then proceed to re-establish
the connection. This is what happens when I issue the `C' and `O'
commands in the server buffer, which work fine, but apparently this is
not happening with Gnus. I'll see if I can catch it happening some time
and do an fstat like you say on the Emacs process.
