The same rational is true here. Your problem deals with "postfix", so your questions should be directed there. There are an extremely knowledgeable group. The author, Wietse Venema, quite often chimes in with answers to user's questions. To join the list, check this out: http://www.postfix.com/lists.html In any case, see these URL's for further info: http://www.postfix.com/DEBUG_README.html http://www.postfix.com/DEBUG_README.html#mail Better, provide output from the postfinger tool. This can be found at http://ftp.wl0.org/SOURCES/postfinger. --=20 Carmel
