Specifies whether the recipient addresses must be parsed strictly
in compliance with RFC 822, which is a specifications document issued by the
Internet Architecture Board.
This setting is not generally used for most mail applications. RFC 822
syntax for parsing addresses effectively enforces a strict definition of a
valid e-mail address. If you select this setting, JavaMail will adhere to
RFC 822 syntax and reject recipient addresses that do not parse into valid
e-mail addresses (as defined by the specification). If you do not select this
setting, JavaMail will not adhere to RFC 822 syntax and will accept recipient
addresses that do not comply with the specification. By default, this setting
is deselected. You can view the RFC 822 specification at the following URL
for the World Wide Web Consortium (W3C): http://www.w3.org/Protocols/rfc822/.
