Improoving spamassassin

prego 2 Kommentare

I’ve got a mailserver running that fetches mails from different accounts via fetchmail, scans them for viruses using clamav, filters for SPAM using spamassassin and then deliveres it to the mailbox and sorts them via procmail. Now Spamassassin just filtered arround 35-40% of all SPAM I recieved. My local.cf includes

use_bayes 1
bayes_auto_learn 1
bayes_auto_lern_threshold_nonspam 1
bayes_auto_lern_threshold_spam 14.00
bayes_ignore_header X-Spam-Flag
bayes_ignore_header X-Spam-Status
In order to recognize more SPAM i created a folder SPAM in my Mailbox and moved all SPAM I recieved into it. Now simply change to that folder and run a sa-learn –spam –progress * there, as well as a sa-learn –ham –progress * in your inbox and voila… SPAM-recognition by spamassassin starts improoving very fast :-)

(Thanks Diederik for the hint)

Ich habe eine Sphinx PICO PCMCIA Bluetooth Karte. PCMCIA Support im Kernel aktiviert, Bluetoothunterstuetzung einkomiliert, serial_cs als Modul. Problem:

Aug 12 12:42:20 alitoh pccard: PCMCIA card inserted into slot 0
Aug 12 12:42:20 alitoh cs: memory probe 0x0c0000-0x0fffff: excluding 0xc0000-0xcffff 0xe0000-0xfffff
Aug 12 12:42:20 alitoh cs: memory probe 0x60000000-0x60ffffff: clean.
Aug 12 12:42:20 alitoh cs: memory probe 0xa0000000-0xa0ffffff: clean.
Aug 12 12:42:20 alitoh pcmcia: registering new device pcmcia0.0
Aug 12 12:42:20 alitoh serial_cs: serial8250_register_port() at 0x03e8, irq 10 failed

Googeln und im Endeffekt die Hilfe von Russel King – Maintainer des serial core des 2.6er Kernels – brachte es dann zu:

Aug 12 12:51:55 alitoh pccard: PCMCIA card inserted into slot 0

Aug 12 12:51:55 alitoh 0.0: ttyS5 at I/O 0x3e8 (irq = 10) is a 16550A

Problemloesung:

Keine freien uart-slots. Abhilfe dagegen schaffte mir den serial-support mit

(8) Maximum number of 8250/16550 serial ports

anstatt von

(4) Maximum number of 8250/16550 serial ports

zu kompilieren, und

8250.nr_uarts=8

als Kerneloption beim booten zu uebergeben.

Naechstes Problem:

alitoh linux # hciconfig dev
Can’t get device info: No such device
alitoh linux #

Loesung:

modprobe hci_uart
setserial /dev/ttyS5 baud_base 9121600
hciattach /dev/ttyS5 any 921600

anschliessend:

alitoh linux # hciconfig dev

Ma gucken ob wir Geraete finden:

Tataaaa… Handy gefunden :-) Mal anpingen…:

Der Rest braucht nicht dokumentiert zu werden. emerge kdebluetooth blabla und alles wunnerbar :-D. Ich muss jetzt nur noch rausfinden, wie ich den ganzen Kram verautomatisiere, aber das kommt auch noch :-)
