Hi!
My brand-new exim on potato kernel 2.2.13 used to
work perfectly for some days. Just before (what a chance!) to go production, it
stopped working on outgoing e-mails, with this nasty message: '550 relaying to <ghostettler@bluewin.ch> prohibited
by administrator (failed to find host name from IP address)', Port : 25,
Sécurisé (SSL) : Non, Erreur de serveur : 550, Numéro d'erreur :
0x800CCC79
I guess it is maybe related to DNS. My simple
problem is "where in the hell do I specify the DNS primary and secondary IP
addresses under Debian Linux ?" Yes, with Windoze NT, it was quite
straightforward, either on the DHCP server, or, for statically addressed
servers, just go to this DNS tab under protocols under NW neighborhood. Just a
kind of knowing where it is. Guess the same under Linux.
I tried to tweak exim.conf, adding a couple of
sites under "relay_domains". All e-mails for these two sites are going out
perfectly, as exim does not try to get thier IPs from their names. That seems to
indicate one more time a DNS problem.
Do I have to change anything in host_accept_relay
(which is actually localhost which points in the hosts file to 127.0.0.1).
Should it be instead of the loopback, the real address of the mail server ???).
The token relay-domains_include_locale_mx=true is commented out, and host_lookup
is set to *.
Any help greatly appreciated!
