Ban scanners IPs from OpenSMTP logs

=> Ban scanners IPs from OpenSMTP logs

If you are an OpenBSD running an OpenSMTP email server, you may want to ban IPs used by bots trying to bruteforce logins. OpenBSD doesn't have fail2ban available in packages, and sshguard isn't extensible enough to support the multiline log format used by OpenSMTP.

Here is a short script that looks for authentication failures in /var/mail/maillog and will add the IPs into the PF table bot after too many failed login.

Reducing Scope Creep

One of the reasons I created this blog/capsule (other than the opportunity to work with the Gemini protocol, text format, and Geminispace) was to encourage me to write more often. I started off well, but slowed down considerably three months or so ago. While there are several reasons for that, I've decided to I concentrate on writing short articles for this blog/capsule and relegate the longer articles for my other blog. I hope this will encourage me to write more. We'll see.
