Remove external links from mails #612
Description
Use inline images (or attachments) for all mail components such as images.
The current institution images are linked from static.surfconext.nl in SVG format.
Some mail providers (Gmail) do not display SVG files, so the image should be fetched, converted, and included.
There are three places in the email where there is a logo:
- At the top of the email
- In the footer
- In a button if it is eduID
The logo at the top of the email is an institution logo. If the institution is SURF, you get a SURF logo; otherwise, you get the logo of the institution.
The institution SURF logo, SURF footer logo, and eduID button are already done.
We still need to add institutionLogoUrl as an inline image.
Tips:
The institution logo comes from Manage and can be set in the metadata fields: Search → IdP → Dummy IdP → Metadata → data.metaDataFields["logo:0:url"]
The logos need to be square (48px × 48px). On test2, this is not always the case.
You can change it to use this one:
