This is no longer applicable, but I may resurrect it again....
Custom News Headers:
For those of you who insist on creating custom headers for your news, that capability has been added. To force rnMac to use a custom header for news postings, just add an 'STR ' resource called "CUSTOMNEWSHEADER" to your settings file; this resource should specify the name or pathname of the textfile that contains your custom header. Of course, for this to be really useful, you will probably want to use some of the following macros in your header (the names are fairly self-explanatory): NODENAME, MAILSERVICE, DOMAIN, TIMEDIFF, USERNAME, REALNAME, DISTRIBUTION, ORGANIZATION, REPLYTO, GROUPNAME, TOADDRESS, SUBJECT, REFERENCES, TICKTIME, DAYNUM, MONTHNUM, DAYNAME, MONTHNAME, HOUR, MINUTE, SECOND, YEAR, TWODIGITYEAR, SEQFNUM. To invoke a macro in your header, just use a percent symbol (%) followed by the macro name in capitals. When rnMac reads in your header file, it replaces the macro with the appropriate string; e.g. "%REALNAME" would be replaced by "Roy Wood" on my machine. As you may have guessed, if you want to place a percent symbol in your header, just type it twice, e.g. "%%". The end of the header, as recognized by rnMac, is the first empty line in the message (i.e. the first line consisting solely of a carriage return).
If you're having trouble with custom headers, take a look at the default header lines, and read RFC-822, RFC-1036, and RFC-976 (stop complaining窶 if you want to do fancy stuff, you have to be prepared to put in a little effort). Note that rnMac does not modify custom headers in any way when they are spooled, so what you see in the edit window is what will be used as the message header!
