Email Filtering

Libra Esva for Office 365

With Office 365, Microsoft is offering a very affordable email hosting service that includes a lot of added tools. Most customers seem happy with the email hosting part. As for the built-in Anti-Spam, there appears to be room for improvement. Office 365 comes with EOP (Exchange On-line Protection) built-in. EOP is Microsoft’s generic Anti-Spam engine and sadly it has completely replaced FOPE (Frontbridge Online Protection for Exchange). Libra Esva for Office 365 fills this gap, offering the best email security solution perfectly fitted with Microsoft Office 365 environment.
