If so, then it'll read until a blank line and assume all are meant to be headers. So the gory solution here is to move the Subject: line up to the top. I assume it won't break anyone elses program or anything anyway (besides, RFC-822 specifies that the *order* of headers is irrelevant). Gahhhhh.... If we have been configured for a smart mailer then we don't want to add a from line. If the user has specified one then we have to honor their wishes. If they've just given a 'from name' then we'll just put in the username and hope the mailer can add the correct domain in. **/ if (!subject) { i = strlen(mailer); if (i > 5 && streq(mailer+i-5, "/mail")) subject = ""; else if (i > 6 && streq(mailer+i-6, "/mailx")) subject = ""; } /* * Emit the message header. */ if (subject) fprintf(ofp, "Subject: %s\n", subject); if (from_addr) { if (from_fullname) fprintf(ofp, "From: %s (%s)\n", from_addr, from_fullname); else fprintf(ofp, "From: %s\n", from_addr); } fprintf(ofp, "Date: %s\n", get_arpa_date()); if (replyto) fprintf(ofp, "Reply-To: %s\n", replyto); fprintf(ofp, "To: %s\n", to_list); if (cc_list) fprintf(ofp, "Cc: %s\n", cc_list); if (references) fprintf(ofp, "References: %s\n", references); if (inreplyto) fprintf(ofp, "In-Reply-To: %s\n", inreplyto); if (comments) fprintf(ofp, "Comments: %s\n", comments); #ifndef NO_XHEADER fprintf(ofp, "X-Mailer: fastmail [version %s PL%s]\n", VERSION, PATCHLEVEL); #endif putc('\n', ofp); /* * Emit the message body. */ while (fgets(buf, sizeof(buf), ifp) != NULL) fputs(buf, ofp); fclose(ifp); fclose(ofp); dprint(1, (debugfile, "executing: %s\n", cmdbuf)); i = system(cmdbuf); (void) unlink(temp_fname); if (i != 0) { fprintf(stderr, catgets(elm_msg_cat, FastmailSet, FastmailErrorSending, "%s: error sending message [%s return status %d]\n"), progname, mailer, i); exit(1); } exit(i); } int addword(dest, destsiz, word, len_p) char *dest; int destsiz; const char *word; int *len_p; { int dlen, wlen; dlen = *len_p; dest += dlen; wlen = strlen(word); if (dlen+1+wlen+1 > destsiz) return -1; if (dlen > 0) { *dest++ = ' '; ++dlen; } for ( ; *word != '\0' ; ++word) { if (*word != ',') { *dest++ = *word; ++dlen; } else { *dest++ = ' '; ++dlen; } } *dest = '\0'; *len_p = dlen; return 0; }
