Brew should have already handled other links, you can test the correct versions with `sudo mysql --version` (if it's something like _mysql  Ver 15.1 Distrib 10.5.5-MariaDB, for osx10.15 (x86_64) using readline 5.1_ it's the correct one) and `sudo nginx -v` (if it's something like nginx version: nginx/1.19.3 it's the correct one)

+#### MailHog
+
+E-mails won't be sent on local environment because there is no email server configured. This is where [MailHog](https://github.com/mailhog/MailHog) comes in.
+
+MailHog should be pre-installed but if not, run following:
+
+``` bash
+brew update && brew install mailhog
+```
+
+Ensure you have the latest [air-helper](https://github.com/digitoimistodude/air-helper) or [MailHog for WordPress](https://wordpress.org/plugins/wp-mailhog-smtp/) activated to enable MailHog routing for local environment.
+
+Then just run:
+
+``` bash
+mailhog
+```
+
+You should now get a log in command line and web interface is available in http://0.0.0.0:8025/.

 ### File sizes
 
 You might want to increase file sizes for development environment in case you need to test compression plugins and other stuff in WordPress. To do so, edit `/usr/local/etc/php/7.4/php-fpm.d/www.conf` and `/usr/local/etc/php/7.4/php.ini` and change all **memory_limit**, **post_max_size** and **upload_max_filesize** to something that is not so limited, for example **500M**.
