I'm getting a "procmail: Missing closing brace" error. The problem seems to occur in the case where sender's address (in this case, the domain part) is in ${NOBOUNCE}. Unfortunately, matching braces in the sb.rc is so confusing (and confuses my editor) that I cannot find which one might be missing. I'm suspecting that to reproduce the problem, you just need to put an address in your ${NOBOUNCE} file and try sending a mail from that address. Thanks.
