I don't have any specific suggestions. As I'm sure you know, you are using a very old version of Netscape, and RFC 2822 does introduce some changes. Here is the summary of changes from that document:

=== Appendix B. Differences from earlier standards

This appendix contains a list of changes that have been made in the Internet Message Format from earlier standards, specifically RFC822 and STD3. Items marked with an asterisk (*) below are items which appear in section 4 of this document and therefore can no longer be generated.

It's hard to make any specific suggestions without being able to see a message that Netscape generates, but perhaps this will give you some leads.

(Incidentally, if you would consider changing mail apps, Mozilla Thunderbird is a descendant, in some sense, of the Netscape mail app. To the extent I can remember, it works in a pretty similar way.)
