Internet Message Format (IMF) is specified by RFC 5322. It defines a variety of header fields, such as To
, From
, and Subject
.
It also defines the Comments
header field and the Keywords
header field.

Does anything actually use these two header fields today, or are they totally superfulous? In other words, are mail clients in modern use expected to make use of these?

I don't know any client that does support them. But I think it would be usefull to enable search by keywords. Instead of indexing the whole text of the message. A good practice well explained in "Everything Is Miscellaneous:" by David Weinberger. – user1708042 – 2018-03-26T12:03:42.930
I'm not sure what actual problem you are facing?
– RedGrittyBrick – 2012-11-14T21:33:55.7401Pretty simple: Comments and Keywords are header available to email clients and servers. As far as I can tell, none of my clients use them. I am wondering if any clients or servers actually use them. – james.garriss – 2012-11-15T14:19:39.773
2I'm not sure why this is considered "not constructive". I'm very curious to know the answer, and answers would certainly be supported by facts and references. – npdoty – 2013-11-21T22:03:53.810
