My problem is: We switched over to Base64 images in configuration setting and it work in segment email but in email sent out via Contact page [Send Email], the image are broken /missing.

These errors are showing in the log: No errors show up

Steps I have tried to fix the problem:
Right now, we have to make sure we disable Base64 setting in Configuration every time we want to send email out using Contact page Send button.
