My company just added 5 of the social networking images to its email signature. Now we have tons of copies of these identical images stored in the software that takes emails and turns them into tickets of some kind (Jira does this, but this isn't the only one we have with this problem).
Is there a way to block these on the SMTP level, or at the Exchange level, if I know the exact image? Maybe there's a way to block a PNG of size 25x25 automatically somehow?
If I stop these at the ticket system level, I will have to do it many times in different places. Still looking for a way to do this at the Exchange level. I found this link after reading the latest answer:
Hoping it or a related topic will have a solution. Thanks again.
Looks like the only way to do this in Exchange is to block by file size, and since they all have different sizes we need 5 rules. This is still simpler for us than blocking at every application point that is storing these images.
Thanks for the help.
