Editorial interest 84/100 Selection signal · not a rating of the site

A native Mac utility that catches development email at 127.0.0.1:1025, keeping test messages away from real customers.

Landing page captured for the 2026-08-21 issue.

Why it surfaced

MailBar turns a familiar developer safeguard into a tiny menu-bar workflow: point an app at its local SMTP server, then inspect rendered HTML, plain text, attachments, and persistent .eml files. It also blocks remote images and scripts, making the tool unusually attentive to both accidental delivery and tracking pixels.
