Okay so you see the classic logs of YLMF and its flooding your logs and server and and and, well after some months of searching, reading, downloading, attempting and crashing of exim <-- LOL I THINK i have finally found a solution for the dreaded YLMF head banging, grey hair highlights, energy drinking, smoked up room, jumping off of roof problem. Did i over do that part oh well. Point is i've tried every block on the exim frontier and it works but that's not how i wanted the block to happen so i turned to a more direct approach. KEEP IN MIND YOU DO THIS, OF COURSE AT YOUR OWN RISK. I HAVE IT AND IT SEEMS TO BE WORKING... SO FAR... You need CSF, but if you good with iptables you can probably insert this directly into the firewall. you must have root access, im not sure about shared servers, your problem i guess Before CSF Rules: if the file doesn't exist, pico it or nano or what ever your flavour and save... csfpre.sh: Create file /etc/csf/csfpre.sh add following command and save: iptables -A INPUT -p tcp --dport 25 -m string --string 'ylmf-pc' --algo bm -j DROP --dport 25 <-- standard smtp port you can change this to what ever your smtp port is multiport blocks: --dport 25,26,465,587 close/save and run: csf -r Okay so that is it, its been working for me and i hope it works for you... sources :
