Stuff & Various Nasty Hacks, Mostly Written in PHP, Not All Written Here, Code That Makes Babies Cry

• assblocker blocks IPv4 addresses of assholes at the local firewall by manual use and automatically by monitoring mail log files. Does not support the shitshow that are IPv6 addresses, which you shouldn't be allowing on mail servers anyway, due to the shitshow of trying to get IPv6 e-mail into the e-mail shitshow known as Google Inc., World's Largest Spammer
  
  
• gfm2html is a script for creating valid HTML documents from Markdown to HTML converters that don't produce valid HTML documents. It is designed for cmark-gfm, but can be used with any other Markdown filter that accepts input on STDIN end emits HTML on STDOUT.
  
  
• ml-web-archiver is a script for generating web pages from mailing list archives, that will not make you want to rip your hair out.  It produces archives similar to pipermail, It is not fancy, but it just works.
  
  
• tmuxie is a small and lightweight tmux session manager (wrapper) written as a POSIX shell script (Bourne, Bash, Dash, ksh,..) forked from screenie for GNU Screen, dual-licensed GPLv2 and BSD.
  
  
• star is the Simple Templates And Renderer HTML template engine for PHP 7.3 and later.  Unlike virtually every other contemporary PHP template engine, star has zero dependencies and you can paste it right into your existing script.  It is simple, unsophisticated code.  star compiles templates to PHP code for optimal performance.
  
  
• check-ssl-certs is a script for monitoring SSL/TLS certificates for expiration.  It can check directories of certificates and it can scan Apache site configuration files for certificates to check.  It can be used as a replacement for the discontinued LetsEncrypt certificate expiration notification email service.
  
  
• weather.php is a script for obtaining a tiny current weather string from a METAR weather station.  It was created to be used with tmux to put the weather into the status bar.
  
  
• dog, better than cat is a PHP port of Jason Cohen and Jacob Leverich's defunct dog.c, an enhanced version of the *nix cat program. Some options intended to amuse have been left out, and some new options added.
  
  
• EggLogging is a BSD-licensed plugin for the Phergie (v2) IRC bot to create text log files for monitored channels in an Eggdrop-compatible format. EggLogging is intended to produce output that can be fed to stats programs like PISG, and log to HTML converters like irclog2html.py .
  
  
• Phailomatic, a PHP-based intrusion prevention system/DoS mitigation tool similar to Fail2ban or Denyhosts.  It is intended to be small, relatively lightweight, and simple.
  
  
• Getmail Retriever plugin for Roundcube is a GPL licensed fork of the ispcp_fetchmail plugin for Roundcube webmail.  getmail is an alternative to fetchmail with a better track record for reliability and security.  This plugin allows your Roundcube users to use getmail to retrieve mail via POP3 or IMAP and deliver that mail to the user.  The back end is a PHP-CLI/PDO script run from cron that executes getmail according to the administrator and user settings.
  
  
• PowerDynDNS for PowerDNS is an under-development, GPLv2 licensed, open source dynamic DNS service, usably compatible with the DynDNS.org API when used in conjunction with PowerDNS.  PowerDynDNS can be combined with PowerTinyDynDNS for compatibility with both the DynDNS.org API and TinyDynDNS.
  
  
• PowerTinyDynDNS for PowerDNS is a GPLv2 licensed, open source dynamic DNS service, usably compatible with the tinydyndns API, when used in conjunction with PowerDNS.  TinyDynDNS can be combined with PowerDynDNS for compatibility with both the DynDNS.org API and TinyDynDNS. As PowerTinyDynDNS uses POP3 email protocol, virtually anything that connects to the Internet is already ready to use with PowerTinyDynDNS.
  
  
• POP-before-SMTP-Auth is a GPLv2 licensed, open source mail log scanner daemon that implements a POP-before-SMTP authorization service for Postfix/Dovecot. It can probably be easily adapted to use other SMTP servers and other POP3 servers.
  
  
• DPopper 1.0 is an original-BSD-licensed 'dummy' POP3 server written in C by Karl Pielorz. It can be used to handle hoards of marauding customers while your real POP3 server is having a bad day. It will appear to authenticate anybody, and will accept any password they offer. It will also tell them they have no new mail, hence provides the backend for 'transparently' failing POP3 servers. (Not written here, but seems to have disappeared from http://tdx.com/software along with their site. Mirrored here because we found it useful with TinyDynDNS.) DPopper is licensed under "the Original BSD License". That's the one with the "advertising clause".

What is here, is here. If it's not, then it's not. If it doesn't work for you, then it doesn't work for you. No promises made about it. But that doesn't mean I won't try to help make it work for you.  there is a mailing list, and list archives, where you can ask questions.  You can find the git repositories at https://code.gothamcode.com, where you can open and view "issues".

Some projects have been temporarily hidden because they need some attention to make them work and/or be available to download.
