I've read Are there .NET Framework methods to parse an email (MIME)? , but since that question is quite old, I'd like to re-ask it:
Do you know of a good (in terms of performance and/or features and/or ease-of-use) and preferably gratis .NET Component that can parse an email message file?
What I really need from the component actually is very simple: I need a way to manipulate (read/write/create) header fields.
However, additional functionalities will also be welcome.
One additional limitation: If the component is in the form of Source Code, it must be in VB.Net.
