[NTLUG:Discuss] Sendmail with Drac authentication.....

[Douglas King]

HELP!  I made a change last night that I THOUGHT (bad idea) to try to 
reduce the SPAM on my mail server.  However, here is what I did.

I removed a setting in the M4 config called " Feature 
FEATURE(`accept_unresolvable_domains')".  Well...thinking that this would 
require reverse DNS, I removed this setting.  Now, folks outside MY network 
get a "relaying denied" message when trying to send a message back out.  I 
use Eudora's POP3 Mail extension to authenticate the POP3 portion, DRAC is 
used to keep the SPAMMERS from accessing the machine (requiring a valid 
account) before delivery.

Now, i can send messages, but "outsiders" cannot.  I have gone in and 
replaced the sendmail.mc file with the "original file" (prior to the 
change), but it still does not work.  Does anyone have any ideas on what 
I've done or HOW can I fix what I have done?

It's already been down 1 full day....time is of the essence.  If you 
respond to THIS request, please also respond to me at daking at dak1.net.

TIA for you help.
