Antispam appliance for an Office 365 environment
Posted on 2014-10-06
Lately at the company we have been bombarded by spam emails and because of it I am looking to install a good antispam appliance, the only thing is that my email environment is a little different.
All of our Mailboxes have been migrated to office 365 but our MX record is still pointing to our on-premises Exchange box. By installing the antispam appliance on top of my Exchange in this environment I am sure it will work as expected.
Now, in a few months, we are looking to migrate our MX to have it point to the Office 365 servers. In this situation, the antispam appliance installed in my company will no longer work since SMTP traffic will be hitting the Office 365 servers only.
This is why i am looking for other means to block spams but I have not had luck yet.
I have query Office 365 for a solution but their answer has always been that the only means of blocking spam is by utilizing their content filtering and connection filtering.
Does someone knows about a good solution for my situation?
