I installed sendmail 5.61 and I lost mail deliver to my local network (machines in the same domain). When I run 5.61 on an address with the -bv flag, sendmail says its deliverable. Using -bt, the address parses correctly. But when I try to send mail, I get a 550 ... Host Unknown message from MAIL-DAEMON. Mail to any uucp or non-local domain site seems to be deilvered fine. Any ideas on what might be wrong? I backed off to sendmail 5.58 and named 4.8 with little to no problems. ----------------------------------------------------------------------- Marc Lesure / Arizona State University / Tempe, AZ "Between the world of men and make-believe, I can be found..."

It probably has to do with your resolv.conf file. Make sure it has a "domain" line. In addition, by invoking sendmail with the -bt flag and also the -d0-99.4 flag, you get to see exactly what queries are being made to your name server. I did this once, and saw things like host.ucar.edu.ucar.edu (double domain sickness). Another thing you can do is to fire up named with debugging. This will probably tell you what is really happening. Another thing is that if you compile sendmail 5.61 without NO_WILDCARD_MX defined, the only queries that ever seem to be made are for CNAMES. Of course, if you do define NO_WILDCARD_MX, then you had better not have a wildcard MX record for your domain, or every single query will succeed even when it is bogus. --Greg
