Package: kmail Version: 4:4.10.5-2 Severity: normal Currently kmail on my system will keep a TCP connection to the mail server open after a message is sent, it stays open until the mail server times out and disconnects it.
I believe that kmail should send a "quit" command to end the session. Keeping the connection open serves no purpose (no great effort or time is taken to establish it) and acts as a minor DoS attack on the server. For example most of the mail servers I run have a maxproc limit for the SMTP service that is significantly smaller than the number of users. If all users on such a network ran kmail and most of them tried to send email within the 5 minute timeout period (which happens at about 5PM in some of the offices where I do sysadmin work) then some users would be unable to connect. -- System Information: Debian Release: jessie/sid APT prefers stable APT policy: (700, 'stable'), (500, 'unstable') Architecture: amd64 (x86_64) Kernel: Linux 3.10-3-amd64 (SMP w/4 CPU cores) Locale: LANG=en_AU.UTF-8, LC_CTYPE=en_AU.UTF-8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/bash Versions of packages kmail depends on: ii kde-runtime 4:4.10.5-1 ii kdepim-runtime 4:4.10.5-2 ii kdepimlibs-kio-plugins 4:4.10.5-1 ii libakonadi-contact4 4:4.10.5-1 ii libakonadi-kde4 4:4.10.5-1 ii libakonadi-kmime4 4:4.10.5-1 ii libakonadiprotocolinternals1 1.9.2-2+b1 ii libc6 2.17-93 ii libcalendarsupport4 4:4.10.5-2 ii libgcc1 1:4.8.2-1 ii libgpgme++2 4:4.10.5-1 ii libincidenceeditorsng4 4:4.10.5-2 ii libkabc4 4:4.10.5-1 ii libkcalcore4 4:4.10.5-1 ii libkcalutils4 4:4.10.5-1 ii libkcmutils4 4:4.10.5-1+b1 ii libkdecore5 4:4.10.5-1+b1 ii libkdepim4 4:4.10.5-2 ii libkdeui5 4:4.10.5-1+b1 ii libkio5 4:4.10.5-1+b1 ii libkleo4 4:4.10.5-2 ii libkmime4 4:4.10.5-1 ii libknotifyconfig4 4:4.10.5-1+b1 ii libkontactinterface4 4:4.10.5-1 ii libkparts4 4:4.10.5-1+b1 ii libkpgp4 4:4.10.5-2 ii libkpimidentities4 4:4.10.5-1 ii libkpimtextedit4 4:4.10.5-1 ii libkpimutils4 4:4.10.5-1 ii libkprintutils4 4:4.10.5-1+b1 ii libksieveui4 4:4.10.5-2 ii libktnef4 4:4.10.5-1 ii libmailcommon4 4:4.10.5-2 ii libmailimporter4 4:4.10.5-2 ii libmailtransport4 4:4.10.5-1 ii libmessagecomposer4 4:4.10.5-2 ii libmessagecore4 4:4.10.5-2 ii libmessagelist4 4:4.10.5-2 ii libmessageviewer4 4:4.10.5-2 ii libnepomukcore4 4:4.10.5-1+b1 ii libpimcommon4 4:4.10.5-2 ii libqt4-dbus 4:4.8.5+git121-g2a9ea11+dfsg1-2 ii libqt4-network 4:4.8.5+git121-g2a9ea11+dfsg1-2 ii libqt4-xml 4:4.8.5+git121-g2a9ea11+dfsg1-2 ii libqtcore4 4:4.8.5+git121-g2a9ea11+dfsg1-2 ii libqtgui4 4:4.8.5+git121-g2a9ea11+dfsg1-2 ii libqtwebkit4 2.2.1-6 ii libsolid4 4:4.10.5-1+b1 ii libsoprano4 2.9.2+dfsg.1-4 ii libstdc++6 4.8.2-1 ii libtemplateparser4 4:4.10.5-2 ii perl 5.18.1-4 Versions of packages kmail recommends: ii gnupg-agent 2.0.22-1 ii gnupg2 2.0.22-1 ii pinentry-gtk2 [pinentry-x11] 0.8.1-1 Versions of packages kmail suggests: pn clamav | f-prot-installer <none> ii kaddressbook 4:4.10.5-2 ii kleopatra 4:4.10.5-2 ii procmail 3.22-21 pn spamassassin | bogofilter | annoyance-filter | spambayes | bsfi <none> -- no debconf information -- To UNSUBSCRIBE, email to debian-qt-kde-requ...@lists.debian.org with a subject of "unsubscribe".
