WordPress AntiSpam Plugin, Configuring Alpine Linux to Send Mail
Published (updated: ) in Uncategorized. Tags: Alpine Linux, Docker, WordPress, WordPress Comment Spam.
The previous incarnation of this blog had a lot more inbound links, and accumulates spam. One day, I had 14,000 comments pending, and most were spam. So, I wrote a tool to help work through the backlog.
It basically worked, but at one point, I had a bug: I had it match a field on ” ” or something like that, and it wiped out most of the comments.
I could have restored it, but it didn’t seem to be worth it.
The code’s a little better now, and slightly safer – but it is still a crude way to get through a spam backlog. It has two features: delete everything matching the blacklisted words, and delete messages where the URLs or email addresses match messages in the Spam list.
Alpine Linux Busybox SMTP Agent
I had some problems sending email from a WordPress installation in an Alpine-based Docker container.
Alpine doesn’t include an SMTP server with a minimal install, but you can use BusyBox to relay to an SMTP server.
