I’ve just sent myself some preview summaries, since I don’t normally get them. I’m seeing some random—but consistent—missing space characters in headings and text within the email. These spaces are not missing in the forum content, but the same ones are consistently dropped in multiple generated pr…

Is it possible this could be a font / display problem? Have you checked the underlying raw content?

Hm. I’m not sure how to diagnose a font/display problem. The emails render the same in multiple mail clients and browsers across Windows and Linux. I’ve attached .json to the forum post URLs, and there’s nothing off about the “topic_slug” or “cooked” content… Is there something else I could be che…

Ok - l looked at the raw email, and where the HTML version is missing spaces, the text version has the correct spaces. However, the text version is missing other space characters.

Thanks for the analysis, Michael! [image] Michael Brown: Can you have Discourse submit mail to a local MTA where you can inspect it in the queue prior to the MTA sending it off to your “actual” email delivery server? I’m not an advanced email admin – I’m running the typical recommended self-…

As noted in edits above , this problem continues with current user-posted content, not just admin cut-&-pasted content — and is now observed with summary, user_replied, and user_posted emails. MailerSend support confirmed the space characters are missing when they receive the request from Discourse …

[image] ToddZ: Outgoing emails still have missing space characters If you can temporarily disable TLS between your server and mailersend, that’ll let you inspect the actual traffic on the wire and it’ll show you whether Discourse is sending the spaces or not, setting this question once and fo…

Thanks Michael – I’m new at “inspecting on the wire” but here’s what I’ve found. MailerSend requires TLS and port 587. So: I created an alternate app.yml to send to a free mailtrap.io account on port 2525 set DISCOURSE_SMTP_ENABLE_START_TLS = false applied the change with: cd /var/discourse ./la…
