postfix: Reject some recipient adresses while using catchall on a domain

Allgemein

If you have a catchall on a domain – like anginf.de – you will probably get spam on some adresses which you would like to exclude from the general catchall. This can be achieved by doing some simple steps.

First you have to create a file /etc/postfix/recipient_block with all those email adresses you want rejected:

spam@anginf.de REJECT
morespam@anginf.de REJECT

To be useable for postfix, you have to postmap this file.

root@host:~# postmap /etc/postfix/recipient_block

In your /etc/postfx/main.cf, add a new line to your smtpd_recipient_restrictions:

hash:/etc/postfix/recipient_block

Now you only have to reload postfix and all mails to those mentioned in /etc/postfix/recipient_block will be rejected:

root@host:~# service postfix reload

Configure IR Remote for ODROID C1

Allgemein 
  1. sed -i 's/debug_enable\ =\ 0/debug_enable\ =\ 1/' /etc/odroid_remote.conf
  2. odroid_remote /etc/odroid_remote.conf
  3. tail -f /var/log/kern.log
  4. Now press the buttons on your IR remote. You will get an error code which changes in the first letters. The last four letters are the factory code.
  5. Replace the ZZZZ in the following with the four letters command and execute the command. 
    sed -i 's/factory_code.*/factory_code\ =\ 0xZZZZ0001/' /etc/odroid_remote.conf
  6. odroid_remote /etc/odroid_remote.conf
  7. tail -f /var/log/kern.log
  8. The custom error code will be replaced by „scancode is ...., invalid key is 0x....„
  9. The LAST two letters of the „scancode“ are the needed keycodes. Enter it under key_begin and repeat_key_begin in your /etc/odroid_remote.conf
  10. odroid_remote /etc/odroid_remote.conf
  11. If you’re satisfied with the result, disable the debug_enable flag again:
  12. sed -i 's/debug_enable\ =\ 1/debug_enable\ =\ 0/' /etc/odroid_remote.conf
  13. And one final last time, run the odroid_remote-program:
  14. odroid_remote /etc/odroid_remote.conf

Here’s my sample /etc/odroid_remote.conf, I configured it using a YAMAHA RV520 remote control:

factory_code = 0x1f000001
work_mode = 0
repeat_enable = 1
repeat_delay = 40
repeat_peroid = 39
release_delay = 121
debug_enable = 1
