Hi there, I'm new to the Listserv. I have just installed Listserv as well as LSMTP in my Local Server which has a static IP . I expalin my problem in detail. I have already registered a domain name called xyz.COM in www.register.com . I created a sub domain caled LISTSERV.xyz.COM I just pointed my Static IP (of my server where Listserv is running) to that domain and I noted that it has been pointed correctly. ******For the MX record I again used the same Domain name LISTSERV.xyz.COM as I'm going to use LSMTP. (Is this correct way? I feel I did a mistake here) So now in my configuration, 1.NODE=LISTSERV.XYZ.COM 2.MY DOMAIN=LISTSERV.XYZ.COM 3.SMTP_FORWARD=LISTSERV.XYZ.COM I started the LISTSERV as well as LSMTP and I received a notification mail (MESSAGE (''Network tables generation process started - be...")[via LSMTP - see ww... ) After that when I tried to send a mail to [log in to unmask], the following error occured. ************************************************************************ Message from yahoo.com. Unable to deliver message to the following address(es). <[log in to unmask]>: a.b.c.d does not like recipient. Remote host said: 551 Message relaying to this domain disabled Giving up on a.b.c.d ******************************************************************************* I could not find out the problem , Please help me to work efficiently with the LISTSERV. Thanks in advance. Thanks Again. Ahmad PILOT MANAGEMENT Hong Kong --------------------------------- Do You Yahoo!? Yahoo! Auctions - buy the things you want at great prices
