Hello,
We are using courier-imap with squirrelmail as our mail client. We are
getting a bunch of the following in our logs:
Jun 5 10:49:36 mail imapd: DISCONNECTED, [EMAIL PROTECTED],
ip=[127.0.0.1], headers=0, body=1224, time=1
I am not sure if this is a problem at all since there has been no user
complaints. Still, I would like to correct it if possible. The answer I
got from courier-imap list (Sam Varshavchik) is that "Squirrelmail
simply terminates the connection to the IMAP server, without sending a
formal logout command."
Strace output is below. Low prio item but would be nice to get rid of
those DISCONNECTED messages.
Thank you.
Eray
