Re: inetd/xinetd and uw-imap trouble [WinMe cygwin 1.3.22]

[Mike Wray <mike dot wray at hp dot com>]

Thanks for the suggestions. I tried both - telnet and running locally.

Using telnet the first time you connect selecting the INBOX is OK,
but logout just hangs. Using ctr-] to get the telnet prompt
and quitting, the connection closes but the imapd process stays up.
If you connect again over telnet this time logout returns the BYE
message from the server (and xinetd logs it exiting) but the connection
does not go away (and is still visible in netstat).

Running imapd from the cygwin shell it works fine, and exits
when you logout.

There were slight differences in the output from imapd in the two
cases - and that made me a bit suspicious. So I hacked imapd
to output some more messages I could look at during logout -
and flush them. This showed that it was hanging in closing the mailbox.
It was an mbx mailbox - so just for fun I tried using unix format instead.
Hey presto - it works. So the problem is something to do with mbx mailboxes.

Of course this still leaves the question of why it works with xinetd
and core dumps with inetd. But life is too short. I'll stick with xinetd
and unix mailboxes for now.

Transcripts below.

On the terminal - works fine. Logout returns the BYE/OK message
and imapd exits.
