Very small font for outgoing mails

Technical assistance
1

Infos:

  • Used Zammad version: 6.5.0-1750254727.9a4644ec
  • Used Zammad installation type: Package
  • Operating system: Debian 12
  • Browser + version: Not really important for that

Expected behavior:

It is regarding font problems with mails send from zammad. The settings for our outgoing mails is Helvetica 12px. So they should be shown like that.

Actual behavior:

They arrive with a very small (9px) font-size.

Steps to reproduce the behavior:

I checked the font size using the Zammad’s Rails Console
Using the admin dock

As well as an old topic about the this:

I checked the current settings for our system:
Setting.get('html_email_css_font')

Output:

"font-family:'Helvetica Neue', Helvetica, Arial, Geneva, sans-serif; font-size: 12px;"

But the actual mails that arrive have a font size that is only 9px (Helvetica).

I read that outlook sometimes causes issues with that.
Is there a way to fix this?

Outlook uses pt (points) not px.
px usually is different smaller/bigger than pt - it depends on the client. If you write with outlook clients only (yikes), use pt values.
