[pmg-devel] [PATCH pmg-api] fix #4211: convert quarantine link mail to template

Thu Oct 3 17:26:25 CEST 2024

thanks for addressing this issue!

the change sadly now makes the mail to only contain a text/html part, w/o
a text/plain alternative (just like the quarantine report sent out to
users - see [0,1]).

Would you be open/motivated to look into rendering the contents as
text/plain as well and adding them in finalize_report?
