With all the constraints and processing, I'll offer yet another option: use the checkpassword password authentication scheme. This will bypass post-authentcation log-sniffing and allow you direct access to username, password and client IP (the last I'm not positive about) at authentication time. Now you'll have everything you need to do any wild and crazy auth processing, including database searches and triggering firewall blocking based on whatever crietria you want (including common password use). As to how to integrate it into your dovecot, I'm not sure whether it's best to supplant the LDAP method and authenticate within the checkpassword script, or to put it as the first authentication method (ahead of LDAP) to get first crack at inspect at authentication data, or the fallback authentication method (after LDAP) to pick up all the failures. However, after running honeypots, I can tell you that although BFD attackers will common use passwords, any static list of abused passwords will miss a lot. (A common one they use is $password=variations($user) or variation($domain)). Number of auth failure limits should also be a criteria for banning. Extinct users are also good candidates for instant banning. Joseph Tam <jtam.home(a)gmail.com>

Because the > list.blocklist.de/lists/all.txt blocks some, but not anywhere near all. There are other RBLs that overlap with this (like CBL), but they include entries will produce false positives. There was OpenBL but that is defunct. The different lists at blocklist.de have varying efficacy: the ssh and smtp BFD detection are fairly good (they have a 90+% hit rate at my site), but the IMAP/POP BFD detection not as good (maybe 20%). However, if people start feeding IMAP/POP fail2ban data back to blocklist.de, that will get better. > I now know how to block large lists of ips, so if anyone has additional > lists to block? Yeah, all of ChinaNet. May produce false positives. Joseph Tam <jtam.home(a)gmail.com>
