I have never seen an MTA reject a message because the sending MTA did not have an MX record. MX records are generally used for sending mail, not receiving. Also, if a MX record is not used, the sending host will attempt the A record.

You may have a different problem. What is the output of trying to send mail from the UNIX box to a 'rejecting host' with the sendmail -v comand line to send a test message?

DUMP_SOCKDFR(8) 					      System Manager's Manual						   DUMP_SOCKDFR(8)

NAME
dump_sockdfr - Display contents of frozen route file for SOCKS server SYNOPSIS
dump_sockdfr [infile] DESCRIPTION
dump_sockdfr reads in a frozen route file for the SOCKS server and produces a listing of its contents on the standard output. The argument is optional; if omitted, /etc/sockd.fr is assumed. The frozen route file is produced by make_sockdfr and is essentially the memory image of the parsed route file. Using the frozen route file can reduce the start-up delay of the SOCKS server program since it no longer has to parse the file contents. When the SOCKS server starts, it always looks for the frozen route file /etc/sockd.fr first. If that file is not found, it then tries to use the plain-text route file /etc/sockd.route. If you use frozen route file, you must remember to run make_sockdfr every time after you modify the plain-text file or the SOCKS server will continue to use the frozen version of a previous route file.
