Use AppleScript or one of the ObjC-Apple event bridges to control 
Mail. For example, using objc-appscript:


#import "MLGlue/MLGlue.h"

// To generate Mail glue: osaglue -o MLGlue -p ML Mail


void CountMessagesInMailbox(MLReference *box) {
   int totalCount, unreadCount;
   NSString *name;
   
   totalCount = [[[[box messages] count] send] intValue];
   unreadCount = [[[box unreadCount] getItem] intValue];
   name = [[box name] getItem];
   printf("Mailbox %s contains %i read and %i unread messages.\n",
           [name UTF8String], totalCount - unreadCount, unreadCount);
}


int main (int argc, const char * argv[]) {
   NSAutoreleasePool * pool = [[NSAutoreleasePool alloc] init];
   int i;
   
   MLApplication *mail = [[MLApplication alloc] initWithBundleID: 
@"com.apple.mail"];
   
   printf("Standard mailboxes:\n");
   CountMessagesInMailbox([mail draftsMailbox]);
   CountMessagesInMailbox([mail inbox]);
   CountMessagesInMailbox([mail outbox]);
   CountMessagesInMailbox([mail sentMailbox]);
   
   printf("\nUser-defined mailboxes...\n");
   int boxCount = [[[[mail mailboxes] count] send] intValue];
   for (i = 1; i <= boxCount; i++) { // note: application references are 
1-indexed
       CountMessagesInMailbox([[mail mailboxes] at: i]);
   }
   [mail release];
   [pool drain];
   return 0;
}


Regardless of what IPC bridge you use, I'd suggest that questions on 
how to perform specific operations on Mail are best directed to the 
AppleScript-users mailing list <http://lists.apple.com/mailman/listinfo/applescript-users
> as that's where most experienced Mail scripters can be found. 
Obviously, any answers you get will be phrased in AppleScript, so 
you'll want to learn the AppleScript language in order to translate it 
back to ObjC. I'd suggest a copy of Matt Neuburg's "AppleScript: The 
Definitive Guide" as a programmer-friendly introduction to the beast. 
I'm also working on ObjC syntax support in ASTranslate (a very handy 
tool that converts AppleScript commands to their appscript 
equivalents) which I hope to have done fairly soon.
