Building RH7.3 server after 7.0 hacked -second request
SECOND REQUEST
Additional information
This does not appear to be just a problem with server (A). I cannot send
mail between any of my three RH7.3 mail servers, but all will send mail
locally, and all will send to / receive from the outside world.
I am using a RH7.3 /etc/mail/sendmail.mc except for commenting out the
DAEMON-OPTIONS line to allow outside mail, and turning off
FEATURE(`accept_unresolvable_domains')
Is there some change to the sendmail in RH7.3 of which I am unaware that
could cause this?
I would appreciate any suggestions of where to even look to solve this
problem.
------------------------------
As some of you may recall from a mid-week email, two of my RH7.0 servers
were badly hacked Tuesday about 5AM, and I lost ssh and think I received a
trojan.
Friday the hacking got worse - all outgoing mail was rejected as "relaying
denied", so
I decided to bite the bullet and format the drive and build a new server.
This was made more interesting by the fact the RH7.3 wouldn't finish
loading packages until I disconnected my second HD which previously held
/var, and my web sites (tried 3-4 times) .. "Kernel unable to reread
partition table on /tmp/hdc (device or resource busy)", then hung
mid-package loading.
Late Saturday afternoon I pulled the plug, and started a RH7.3 install.
Midmorning I was done, including security patches and had no internet
connection .. couldn't even ping from the server. Fortunately, it was just
my ISP picking this time to be down for the first time in months.
Now I have one remaining problem which over 8 hours of work has clarified,
but not solved.
For background, I have the just rebuilt RH7.3 server (A), and two other
recently built RH7.3 servers (B) and (C) at a different location and each
with its own static IP#, all running sendmail for one or several domains
From A - incoming mail seems to be fine
From A - I can send mail locally to several domain names that are on the A
server
From A - I can send email (such as this) out into the world
Through A - I have several email addresses which are accessed by others
from outside and send mail to another
outside address in virtusertable or to an alias which is a list of
outside addresses, and these are working
From A - I cannot send mail to any of the domains at B or C
When I try, I get this on the A sendmail log:
Oct 27 19:02:56 bach sendmail[3693]: g9S02uO03693:

Dick, Did you add a 'sendmail: ALL' to your /etc/hosts.allow? (I believe that a big difference in sendmail between RHL 7.0 and 7.1 ff was linking against libwrap [TCP Wrappers]) -Peter Gutowski

Modified /etc/hosts.allow on two of the servers, and restarted both sendmails (not sure if that was needed) -- no change. This ONLY happens between my own RH7.3 servers, the sending sendmail log says "DSN: Local configuration error" and "SYSERR(root): <destination domain> config error: mail loops back to me (MX problem?)" -- but I don't use MX records Any other differences after RH 7.0 ?? This all used to work between two RH7.0 servers Dick
Hi Dick, Did you add the local system's name to /etc/mail/local-host-names? jim
