Password reset emails not being set

It seems the default PHP docker container cannot send mail.

Some helpful-looking pages:

• https://r.je/sendmail-php-docker
• https://stackoverflow.com/questions/47247952/send-email-on-testing-docker-container-with-php-and-sendmail

I almost got something similar working on wiki.whatwg.org using this recipe: whatwg/wiki.whatwg.org@28725a6

It worked when trying locally but failed when trying live due to what some Googling said was a permissions error. The next step would be trying to fix the permissions in various ways such as https://unix.stackexchange.com/a/605314/190444 .

However instead I went with a different approach of having Mediawiki use our SMTP server directly instead of using ssmtp, in whatwg/wiki.whatwg.org@c6c3f93.

So for the blog we have two paths:

• Try to use ssmtp so that PHP's mail() function works, similar to what I tried first with the wiki.
• Try to make WordPress use SMTP directly instead of PHP mail(). The canonical way to do this seems to be using the "WP Mail SMTP" plugin. The most helpful article I found for that (including tips on ow to configure it without using the GUI) is https://help.dreamhost.com/hc/en-us/articles/215526937-Configuring-the-WP-Mail-SMTP-plugin .

To be continued, probably...

Step 3 of https://www.e-tinkers.com/2020/09/simple-steps-to-setup-wordpress-smtp-email-without-a-plugin/ is promising as an even easier path. It implies that we need to do steps 1 and 2 also but I am skeptical; maybe some version of step 3 alone would suffice.

I seem to have a local branch with the following changes: an entrypoint.sh with

#!/bin/bash
set -euo pipefail

cat >> /etc/ssmtp/ssmtp.conf <<-EOCFG
# Fastmail setup
mailhub=smtp.fastmail.com:465
AuthUser=${FASTMAIL_USERNAME}
AuthPass=${FASTMAIL_PASSWORD}
AUthMetod=PLAIN
UseTLS=YES
UseSTARTTLS=NO
FromLineOverride=YES
EOCFG

docker-php-entrypoint apache2-foreground

and the following diff:

diff --git a/Dockerfile b/Dockerfile
index ff70209..cb4bf26 100644

I have no recollection of whether these were working or when I was working on this, but it's probably better to dump them here than to just blow away my local branch forever.
