Alright, done. In the "weird things I discovered while doing this" ... I saw in slocal that when mail is delivered to a process via a pipe, right after fork() and right before exec(), it uses dup2() to duplicate the file descriptor pointing to the input message down to 0 (expected), opens /dev/null and redirects standard output and standard error to it (expected), but ALSO uses dup2() to make an additional copy of the input file descriptor to descriptor 3 (!). Does anyone know why? It looks like it has always done this. --Ken -- nmh-workers https://lists.nongnu.org/mailman/listinfo/nmh-workers
