Hello. I need to decode a SPAMCAUSE looong string . How can i do this ?
Hello. I need to decode a SPAMCAUSE looong string . How can i do this ?
It depends: how long is this long string? You could copy-paste it into the python code and use it as value to assign to a variable (instead of passing it as an argument).
You could just use this main program, instead of using the sys.argv-approach:
spamcause = <your very long string between quotes>
print(decode(spamcause))
an other way to use this script:
- feed spamcause header in a file whithout "X-VR-SPAMCAUSE: "
- then run
python3 ./ovh-spam-cause.py $(cat /tmp/temp-file) | sed -e "s/;/\n/g"
Here's an online version : https://f3hj7s.csb.app
Hi, I have been using the online version which was working fine @revolunet -> Thx by the way !
But things have changed since a couple of weeks. I can't decode anymore, the code changed. any idea how to fix this ?
Thanks in advance :)

Hello,
Can your share code at github ?
The offset characters (c..g) are alternatingly appended and prepended. So instead of just checking if one of them is in the pair, it is necessary to differentiate between, e.g., fh and hf, by keeping track of even or odd pairs.
