I've hit an odd problem with qmail-remote. With one of our ISP's DNS servers set as primary, qmail-remote will hang indefinitely on some addresses. The DNS server in question responds fine to dig queries. Example: First DNS server in resolv.conf is 205.152.0.20 Run the following command: (testfile contains a email message) cat testfile | /var/qmail/bin/qmail-remote mindspring.com [EMAIL PROTECTED] [EMAIL PROTECTED] qmail-remote will hang forever. If I change the primary DNS server to another one then everything works fine. An strace of qmail-remote shows: connect(3, {sin_family=AF_INET, sin_port=htons(53), sin_addr=inet_addr("205.152.0.20")}}, 16) = 0 send(3, "\250t\1\0\0\1\0\0\0\0\0\0\nmindspring\3com\0\0\377\0\1"..., 32, 0) = 32 time(NULL) = 996696004 poll([{fd=3, events=POLLIN, revents=POLLIN}], 1, 5000) = 1 recvfrom(3, "\250t\203\200\0\1\0\25\0\0\0\0\nmindspring\3com\0\0\377"..., 513, 0, {sin_family=AF_INET, sin_port=htons(53), sin_addr=inet_addr("205.152.0.20")}}, [16]) = 503 close(3) = 0 socket(PF_INET, SOCK_STREAM, IPPROTO_IP) = 3 connect(3, {sin_family=AF_INET, sin_port=htons(53), sin_addr=inet_addr("205.152.0.20")}}, 16) = 0 writev(3, [{"\0 ", 2}, {"\250t\1\0\0\1\0\0\0\0\0\0\nmindspring\3com\0\0\377\0\1"..., 32}], 2) = 34 read(3, and dies there. I wouldn't expect a DNS server to be able to kill qmail-remote. Make it exit with an error, sure. Our setup is qmail-1.03 on a Linux server. The DNS patch has been applied. Any thoughts appreciated... --Brian ------------------------------------------------------ FarPoint Technologies Phones: Tech Supt. - 919-460-1887 Sales - 800-645-5913 Main - 919-460-4551 FTP - ftp.fpoint.com /fpoint.com WEB - www.fpoint.com Sales email: [EMAIL PROTECTED] Technical support: [EMAIL PROTECTED] -------------------------------------------------------
