Ok so i work for an MSP and one of the companies we support is at a managed building. They have bought a printer which they want to use scan to email on.
When going through the setup a week ago it worked perfectly fine and the day after that it suddenly stopped with no changes made by us.
i used the Shields UP Port scanner and last week only the ping reply failed but after telling them to get the port unblocked, now the Solicited TCP Packets has also failed.
Am i right in assuming the building is blocking port 587 so we can't use scan to email?
They have a printer themselves downstairs where they charge like 35p per email so i assume they're actually blocking the port or am i on a competently different planet?
