I'm seeing the same thing again. Although none of the mail servers are down, I can clearly see that the one that IMail is choosing is NOT the one with the lowest priority. I may be missing something, but this seems to be very similar to what Chris is experiencing. Sending and receiving servers are both IMail 7.10 and 7.11 respectively. I am an administrator on both machines.
First off, IMail SMTP is configured to use only one DNS server (216.144.25.2). From that server, I did the following lookup on the target domain (lms.kent.edu): C:\>nslookup Default Server: ns1.gambit.net Address: 216.144.25.2 > server 216.144.25.2 Default Server: ns1.gambit.net Address: 216.144.25.2 > set type=mx > lms.kent.edu Server: ns1.gambit.net Address: 216.144.25.2 Non-authoritative answer: lms.kent.edu MX preference = 15, mail exchanger = smtp04.net.kent.edu lms.kent.edu MX preference = 20, mail exchanger = smtp04.net.kent.edu lms.kent.edu MX preference = 5, mail exchanger = imail.lms.kent.edu lms.kent.edu MX preference = 10, mail exchanger = smtp05.net.kent.edu smtp04.net.kent.edu internet address = 131.123.250.220 smtp04.net.kent.edu internet address = 131.123.250.220 imail.lms.kent.edu internet address = 131.123.20.12 smtp05.net.kent.edu internet address = 131.123.250.221 > OK...easy to see that the MX records are coming back in the wrong order. Lowest priority is imail.lms.kent.edu (preference 5). But by the "super-debugged" log entries below, it seems IMail is delivering to smtp05.net.kent.edu which is the second one in priority order (but last in order they are returned?!): 07:30 14:20 SMTPD(00A9017E) [216.144.25.34] connect 131.123.20.67 port 2482 07:30 14:20 SMTPD(00A9017E) [131.123.20.67] EHLO tryan 07:30 14:20 SMTPD(00A9017E) [131.123.20.67] MAIL FROM: <[EMAIL PROTECTED]> 07:30 14:20 SMTPD(00A9017E) [131.123.20.67] RCPT TO: <[EMAIL PROTECTED]> 07:30 14:20 SMTPD(00A9017E) [131.123.20.67] D:\IMAIL\spool\Dd8d300a9017e217a.SMD 649 07:30 14:20 SMTP-(00000059) [x] Description: WinSock 2.0 07:30 14:20 SMTP-(00000059) [x] official name shemp.gambit.net 07:30 14:20 SMTP-(00000059) processing D:\IMAIL\spool\Qd8d300a9017e217a.SMD 07:30 14:20 SMTP-(00000059) sender <[EMAIL PROTECTED]> 07:30 14:20 SMTP-(00000059) recip is <[EMAIL PROTECTED]> 07:30 14:20 SMTP-(00000059) [x] looking up lms.kent.edu in HOSTS and MX 07:30 14:20 SMTP-(00000059) [x] looking up lms.kent.edu in HOSTS and MX 07:30 14:20 SMTP-(00000059) closed D:\IMAIL\spool\_d8d300a9017e217a.~MD - 1 07:30 14:20 SMTP-(00000059) R<[EMAIL PROTECTED]> - 1 07:30 14:20 SMTP-(00000059) [x] doing direct send lms.kent.edu 07:30 14:20 SMTP-(00000059) Trying lms.kent.edu (0) 07:30 14:20 SMTP-(00000059) [x] delivery to host lms.kent.edu 07:30 14:20 SMTP-(00000059) [x] using source IP for gambit.net [216.144.25.34] 07:30 14:20 SMTP-(00000059) Connect lms.kent.edu [131.123.250.221:25] (1) 07:30 14:20 SMTP-(00000059) 220 smtp05.net.kent.edu ESMTP Sendmail 8.11.2/8.11.2; Tue, 30 Jul 2002 14:15:34 -0400 07:30 14:20 SMTP-(00000059) >EHLO gambit.net 07:30 14:20 SMTP-(00000059) 250-smtp05.net.kent.edu Hello gambit.net [216.144.25.34], pleased to meet you 07:30 14:20 SMTP-(00000059) 250-ENHANCEDSTATUSCODES 07:30 14:20 SMTP-(00000059) 250-8BITMIME 07:30 14:20 SMTP-(00000059) 250-SIZE 10000000 07:30 14:20 SMTP-(00000059) 250-DSN 07:30 14:20 SMTP-(00000059) 250-ONEX 07:30 14:20 SMTP-(00000059) 250-ETRN 07:30 14:20 SMTP-(00000059) 250-XUSR 07:30 14:20 SMTP-(00000059) 250 HELP 07:30 14:20 SMTP-(00000059) >MAIL FROM:<[EMAIL PROTECTED]> 07:30 14:20 SMTP-(00000059) 250 2.1.0 <[EMAIL PROTECTED]>...
