Our company is having an issue with a vendors signature in email that we receive from one of their employees. Basically, the email delivers fine, but when we try to open it, it takes about 30 seconds for the email to preview or open and during the time it gives an error trying to contact server for information then it opens, but the graphic in the vendors signature has an x .
This only occurs for one of the employees at that vendors all other email from this vendor opens fine. I think I may have found the issue but not sure. The ones that work are jpeg graphic and the one that has the delay is a png.
Any thoughts. On our side or their side?
