Last active: Dec 08 2014 11:18 PMI wrote this script to log into POP3 mail accounts, check for unwanted senders and delete those mails automatically to keep my inbox clean.
It's only a proof of concept, a delete function isn't there atm.
It instead produces a debug text file with detailed info on the received server messages and recognised header data.
It's based on the winsock2 lib, but I shortened a lot of stuff to get a better understanding of the code. Basic error checking is still there, but it doesn't evaluate the given account data.
Sorry for the long lines of code here and there.
I haven't checked if ssl works via stunnel.
Edit:
Updated the code. The line to delete mails when a filter match occurs is still commented out.
It also keeps running and checks for mail every 60000 ms instead of closing after the first check.
Added a sample file for email notification in the task tray. The number of undeleted mails is handed over and shown as tooltip. When double clicked, it opens outlook express.
Edit 2:
Decoding of Q-encoded subject lines should work now. Filters for certain words in the subject can be added as needed.
; Email spam killer proof of concept
; Checks multiple accounts against a FilterList based an sender's address
; It logs into the accounts, and checks each mail's From, To and Subject field
; and produces debug output in Email-Check_Log.txt in the same directory
; Delete function line 79 but commented out
;
; Based on code by DerRaphael and some others
