+
+Please refer to [the documentation](https://github.com/axllent/mailpit/wiki/Testing-Mailpit) of how to easily test email delivery to Mailpit.
+
+
 ### Configuring sendmail
 
-There are several different options available:
-
-You can use `mailpit sendmail` as your sendmail configuration in `php.ini`:
-```
-sendmail_path = /usr/local/bin/mailpit sendmail
-```
-
-If Mailpit is found on the same host as sendmail, you can symlink the Mailpit binary to sendmail, eg: `ln -s /usr/local/bin/mailpit /usr/sbin/sendmail`  (only if Mailpit is running on default 1025 port).
-
-You can use your default system `sendmail` binary to route directly to port `1025` (configurable) by calling `/usr/sbin/sendmail -S localhost:1025`.
-
-You can build a Mailpit-specific sendmail binary from source (see [building from source](https://github.com/axllent/mailpit/wiki/Building-from-source)).
+Mailpit's SMTP server (by default on port 1025), so you will likely need to configure your sending application to deliver mail via that port. A common MTA (Mail Transfer Agent) that delivers system emails to a SMTP server is `sendmail`, used by many applications including PHP. Mailpit can also act as substitute for sendmail. For instructions of how to set this up, please refer to the [sendmail documentation](https://github.com/axllent/mailpit/wiki/Configuring-sendmail).
 
 
 ## Why rewrite MailHog?
 
-I had been using MailHog for a few years to intercept and test emails generated from several projects. MailHog has a number of severe performance issues, many of the modules are horribly out of date, and other than a few accepted MRs, it is not actively developed.
+I had been using MailHog for a few years to intercept and test emails, but experienced a number of severe performance issues. Many of the frontend and Go libraries are very out of date, and the project [is no longer maintained](https://github.com/mailhog/MailHog/issues/442#issuecomment-1493415258).
 
-Initially I started trying to upgrade a fork of MailHog (both the UI as well as the HTTP server & API), but soon discovered that it is (with all due respect) very poorly designed. It is over-engineered (split over 9 separate projects) and has too many unnecessary features for my purpose. It performs exceptionally poorly when dealing with large amounts of emails or processing any email with an attachment (a single email with a 3MB attachment can take over a minute to ingest). The API also transmits a lot of duplicate and unnecessary data on every message request for all web calls, and there is no HTTP compression.
+Initially I tried to upgrade a fork of MailHog (the UI, the HTTP server and the API), but discovered that it is (with all due respect to its authors) far too complex. I found it over-engineered (split over 9 separate projects), and performs very poorly when dealing with large amounts of emails or emails with attachments (a single email with a 3MB attachment can take over a minute to ingest). Finally the API transmits a lot of duplicate & irrelevant data on every browser request, all without any HTTP compression.
 
 In order to improve it I felt it needed to be completely rewritten, and so Mailpit was born.
