If you are speaking of the Sendmail MTA, you're asking on the wrong list. But I can save you a bit of time by advising you to look at setting the "smarthost" option. If you are speaking of sendmail(1) submission in a Postfix MTA, there's no trivial way to distinguish how such mail is routed vs. other forms of submission. If you want to route all mail from that Postfix through a different Postfix, it is simple: main.cf : relayhost = [different.postfix.hostname.or.IP] Reference: http://www.postfix.org/postconf.5.html#relayhost The MX records do not affect sending mail unless you configured a non-default setting somewhere. These two links might help: http://www.postfix.org/BASIC_CONFIGURATION_README.html#relayhost http://www.postfix.org/STANDARD_CONFIGURATION_README.html If you do have a Postfix issue, it usually is best to begin by describing the problem and goal in real, non-technical terms. Your followup should be made in accordance with these guidelines: http://www.postfix.org/DEBUG_README.html#mail -- http://rob0.nodns4.us/ -- system administration and consulting Offlist GMX mail is seen only if "/dev/rob0" is in the Subject:
