We have a standard email signature template that all of our employees use. Part of that signature is an image of our logo which is linked to our website.
Over the last couple of weeks some of our users are experiencing issues where their emails to certain individuals are not being received. I've traced this back to the signature and the logo with the link. If that is removed the emails go through correctly.
We use O365 for our email but I'm wondering if gmail or some other large email hosting provider has begun blocking or at least flagging as spam email that that has images with embedded links.
Has anyone else experienced this issue recently? While I know how to get around I haven't been able to determine why it only started happening in the last 2-3 weeks.
