Will MX UTM protect my Network from going E-mail Blacklisted?

[Ahmad_Qattan]

Hi, I've a network where i share the internet connection between the Staff and hotel Guests. and for sure i can not control the Guests network. so i expect to have infected devices to connect to this Guest Network, and to start sending floods of spams to the Internet. and it is a matter of time that the WAN IP Address of the internet connection will be black listed. is there a configuration on the MX to delete such type of traffic? Thanks

Just block port 25.  No respecting system uses that for users email anymore.

Hi, this could be considered as an option. but when i have a Guests LAN, i can not do this. out of question in my case. Thanks

If you are not willing to block port 25 or filter SMTP traffic for your guests, then no, the MX does not do what you're looking for.
