pop3 and imap problem

Hi all

I have a Redhat 8 box running sendmail-8.12.8-9.80. I use both imap and pop3 for clients to donwlaod mails. imap is used by some application related stuff. The users use opp3 to download their mails. The problem started a yesterday when 1 user complained that he was not able to download his mails:
I noticed the following in the /var/log/maillog:
Dec 2 17:27:49 MUSTANG ipop3d[16579]: Login user=<<username>> host=<<IP>>.cox.net [<<IP>>] nmsgs=1/1
Dec 2 17:29:54 MUSTANG ipop3d[16579]: Connection reset by peer while reading line user=<<username>> host=<<IP>.cox.net [<<IP>>]

All subsequent login attempts have had:
Dec 2 17:34:36 MUSTANG ipop3d[16669]: Login user=<<username>> host=<<IP>>cox.net [<<IP>>] nmsgs=1/1
Dec 2 17:38:40 MUSTANG ipop3d[16669]: Command stream end of file while reading line user=<<username>> host=<<IP>>cox.net [<<IP>>]

Only this one user has been having this problem.

Also there is a similar problem with the user that is using imap to poll a mailbox. He is however able to poll the mailbox and retrieve the mail.

What could be the cause of this? And how can I rectify this?

I did so some resaerch and could not find a satisfactory answer. The one answer I got was from http://www.polarhome.com:793/manual/...evel-2001a/FAQ
Said that this was due to the client not terminating the connection properly! But then how could it have started suddenly. The user has always been using the saem mail client for polling his mailbox\ (outlook express 6).

Thanx

GIT-IMAP-SEND(1)						    Git Manual							  GIT-IMAP-SEND(1)

NAME
git-imap-send - Send a collection of patches from stdin to an IMAP folder SYNOPSIS
git imap-send [-v] [-q] [--[no-]curl] DESCRIPTION
This command uploads a mailbox generated with git format-patch into an IMAP drafts folder. This allows patches to be sent as other email is when using mail clients that cannot read mailbox files directly. The command also works with any general mailbox in which emails have the fields "From", "Date", and "Subject" in that order. Typical usage is something like: git format-patch --signoff --stdout --attach origin | git imap-send OPTIONS
-v, --verbose Be verbose. -q, --quiet Be quiet. --curl Use libcurl to communicate with the IMAP server, unless tunneling into it. Ignored if Git was built without the USE_CURL_FOR_IMAP_SEND option set. --no-curl Talk to the IMAP server using git's own IMAP routines instead of using libcurl. Ignored if Git was built with the NO_OPENSSL option set. CONFIGURATION
To use the tool, imap.folder and either imap.tunnel or imap.host must be set to appropriate values. Variables imap.folder The folder to drop the mails into, which is typically the Drafts folder. For example: "INBOX.Drafts", "INBOX/Drafts" or "[Gmail]/Drafts". Required. imap.tunnel Command used to setup a tunnel to the IMAP server through which commands will be piped instead of using a direct network connection to the server. Required when imap.host is not set. imap.host A URL identifying the server. Use a imap:// prefix for non-secure connections and a imaps:// prefix for secure connections. Ignored when imap.tunnel is set, but required otherwise. imap.user The username to use when logging in to the server. imap.pass The password to use when logging in to the server. imap.port An integer port number to connect to on the server. Defaults to 143 for imap:// hosts and 993 for imaps:// hosts. Ignored when imap.tunnel is set. imap.sslverify A boolean to enable/disable verification of the server certificate used by the SSL/TLS connection. Default is true. Ignored when imap.tunnel is set. imap.preformattedHTML A boolean to enable/disable the use of html encoding when sending a patch. An html encoded patch will be bracketed with <pre> and have a content type of text/html. Ironically, enabling this option causes Thunderbird to send the patch as a plain/text, format=fixed email. Default is false. imap.authMethod Specify authenticate method for authentication with IMAP server. If Git was built with the NO_CURL option, or if your curl version is older than 7.34.0, or if you're running git-imap-send with the --no-curl option, the only supported method is CRAM-MD5. If this is not set then git imap-send uses the basic IMAP plaintext LOGIN command. Examples Using tunnel mode: [imap] folder = "INBOX.Drafts" tunnel = "ssh -q -C user@example.com /usr/bin/imapd ./Maildir 2> /dev/null" Using direct mode: [imap] folder = "INBOX.Drafts" host = imap://imap.example.com user = bob pass = p4ssw0rd Using direct mode with SSL: [imap] folder = "INBOX.Drafts" host = imaps://imap.example.com user = bob pass = p4ssw0rd port = 123 sslverify = false EXAMPLE
To submit patches using GMail's IMAP interface, first, edit your ~/.gitconfig to specify your account settings: [imap] folder = "[Gmail]/Drafts" host = imaps://imap.gmail.com user = user@gmail.com port = 993 sslverify = false You might need to instead use: folder = "[Google Mail]/Drafts" if you get an error that the "Folder doesn't exist". Once the commits are ready to be sent, run the following command: $ git format-patch --cover-letter -M --stdout origin/master | git imap-send Just make sure to disable line wrapping in the email client (GMail's web interface will wrap lines no matter what, so you need to use a real IMAP client). CAUTION
It is still your responsibility to make sure that the email message sent by your email program meets the standards of your project. Many projects do not like patches to be attached. Some mail agents will transform patches (e.g. wrap lines, send them as format=flowed) in ways that make them fail. You will get angry flames ridiculing you if you don't check this. Thunderbird in particular is known to be problematic.
