New RblFilter class to perform spam filtering using DNS RBLs.
Better support of certificates in Microsoft .NET Core and Xamarin. Can now use client certificates in SSL/TLS connections and DKIM.
Imap.SetSeenForEntireMessages is now false by default. This means MailBee won't set SEEN flag when downloading entire messages unless you change this property value.
New Global.DnsServers property to override the default list of DNS servers assigned for the current system. Useful if DNS server autodetection is not supported on the current platform (e.g. Xamarin).
New TimeStamp.IP property which represents the IP address the message came from.
Improved autodetection of inline images in Outlook .MSG files.
