One of my customers is having a problem with blocking some e-mails.
Basically they want to block the e-mails which have domain names as
their display names.
Let's say that the domain is "test.com.tr". And my customer wants to block the e-mails which is coming from "ANY" domain but has "xxx@test.com.tr" as their display name.
I've learned that it can be done only with Hybrid but it's a problem for the customers who don't want to send their e-mails to the Cloud. So we need to make it on the ESG.
