Deleting an article on IMAP server

Deleting an article on IMAP server

[Arcady Genkin]

I have to go through this at least once every day.  I open an article
in an nnimap group, then leave it open and switch to doing something
else for a while.  Then when I come back, and try to delete the
article, I get an error (the following backtrace):

Signaling: (error "Process not open for writing" #<network connection "imap" (143 . "soup") state:exit>)
  process-send-string(#<network connection "imap" (143 . "soup") state:exit> "4089 UID STORE 972 +FLAGS (\\Deleted)\r\n")
  imap-send-command-1("4089 UID STORE 972 +FLAGS (\\Deleted)")
  imap-send-command("UID STORE 972 +FLAGS (\\Deleted)" nil)
  imap-send-command-wait("UID STORE 972 +FLAGS (\\Deleted)")
  imap-message-flags-add("972" "\\Deleted")
  nnimap-request-expire-articles((972) "mail/private" "soup" force)
  gnus-request-expire-articles((972) "nnimap+soup:mail/private" force)
  gnus-summary-delete-article(nil)
  call-interactively(gnus-summary-delete-article)

I guess the connection to the IMAP server expires, but that's just a
guess.  I have to tick the message, leave the group, re-enter it, and
delete the message.  This raises two questions:

1. Is this a bug or limitation of IMAP protocol/backend?
2. Is there a way to work around this without doing the
tick-exit-enter-delete sequence?

I'm using Gnus 5.8.7 under Xemacs 21.1.11 and UofW IMAP server.

Thanks!

Thanks, Simon.  This seems to work now!
