C# Class Tickster.Validation.Rfc822AddressValidator

A high-performance email address validator that validates most email address formats specified in RFC 822. Outperforms several non-trivial (interpreted) regular expression based validation methods.

The Validation methods are thread safe in the sense that they do not share any validation state but the configuration properties of the validator may affect the validator in a way that causes invalid addresses to be considered valid (and vice-versa) if they are modified while an address is being validated.

Instantiation is cheap after first init (when the static constructor has completed) so there's really no need share validators across threads but as long as you don't touch the config properties after instantiation you should be safe.

This class doesn't currently support the full address token (mailbox/group). It only supports the addr-spec (local-part "@" domain) and has no support for specifying routes
