how to block access to all webmail except 365 and gmail from one ip address - On Sophos UTM

Chào Peter,

I suspect you'll need to get info from Gmail and Microsoft to find out what subnets and/or 'DNS Group' definitions you'll need to allow from the one user.  After that firewall rule, you'll want another rule to block 'Email Messaging' from that user to 'Internet'.

PS Should someone move your thread to the Network Protection forum?

I choose to block all webmail, all webmail is blocked and exception 365 because in sophos utm there is already exception 365 but not except Gmail

Hi Peter, 

You may visit this KB from Google on what to whitelist from specific Google Mail domains and can be configured from the firewall side in order for Gmail to be exempted: https://support.google.com/a/answer/9497877?hl=en

Hope this helps and thank you for choosing Sophos
