"inbox closed due to access error" message

[david]

That is the error message that I routinely get. Not a show stopper - I can
always reopen the mailbox, but I'm curious if there are settings that
manage this. It usually happens after I click cntl-x to send a message.
I'm using PC version on a Windows computer. The issue happened in Pine, in
Alpine 1 and now in Alpine 2. Again, nothing is lost - it's more an
aggravation that I would like to fix - if possible. My email setup is IMAP,
although it also happens for POP. thanks for any tips...

A guess is that it is probably related to a NAT between you and the
Internet, and that NAT is closing the connection after some amount of idle
time. It's very difficult to debug, though. You might try decreasing the
Mail Check Interval in alpine which would hopefully make it less likely
that the NAT thinks it should close down a connection. Or maybe the NAT
closes down the connection when you connect to the SMTP server to send the
mail, though that seems less likely.

On 27 Aug 2008 david read the comp.mail.pine post of Steve Hubert, which
stated...

thanks for the tip. I had been increasing the interval time, as I didn't
want to place undue stress on the server. Since I don't care about
checking mail every few seconds, I had set the interval at a high value.
I'll try a low value instead. Again, wasn't a crisis, but an annoyance.
Thanks again for the tip.

I have a similar problem, but it is caused by a vpn-connection to the
server on which I have my remote config sometimes being dropped. I have to
quit and restart alpine after restarting the vpn to recover...

That trick won't work for me; is there anything I could do so I don't have
to restart alpine after restarting the vpn? (Just thought about moving
the remote config to a different non-vpn-path server...)
