MailBee.NET Objects v11.1 adds spam filtering via DNS RBL

Tuesday, 06 June 2017

We're pleased to announce the new release of MailBee.NET Objects, now with DNS RBL spam filtering. With just a few lines of code you can now check if an e-mail message originated from a blacklisted IP address.

We also improved certificates and DKIM support in .NET Core, Xamarin and UWP and made various enhancements to Outlook .MSG file processing.

Important note regarding IMAP. Now, when entire e-mails are downloaded with DownloadEntireMessage and DownloadEntireMessages methods, they won't be marked as read automatically unless you set SetSeenForEntireMessages property value to true.

This version does not introduce new license keys, you can keep using your existing MN110 key.
