I have deployed Sophos XG v16 at home incoming mail for my exchange works as well as sending through other exchange servers. Howevee if I try and use my phone or computer to send email from my yahoo or google accounts using their SMTP servers it doesn't work the mail just sits there and I see no logs on the XG. I have messed around with the rules and turned them off but nothing seems to work. Until I connect to another network.
