1. relay allowing *.com in 8.9.1a?
I've been working with relay stuff for a bit now (as I guess we all
have!), and have stumbled onto an interesting thing with my 8.9.1a
config.
It's always allowing relays from *.com, although .com is not in
relay-domains (well, not on its own anyway :) ). It prevents
relaying from *.org, *.au etc etc, just *.com always gets through.
There's .org sites in my cw, relay-domain and virtusertable,
just like the .com ones.
I don't think I explained that very well.
If I telnet in to the box from anywhere (say for example my
home machine, in .au), and do the following this is what happens :
But not only am I coming in from a remote node that is in a
different TLD, but there's no foo.com or bar.com in any MX
records, virtusertable, CW records etc on that server. We'll
get ORBS'd! (or worse, used as a spam relay again!). It seems to
do the same thing for anything that's a valid .com domain.
A similar test but substituting org for com works as expected
(relaying denied).
My config has the following options defined :
divert(0)dnl
VERSIONID(`$Id: test.mc,v 1.6 1998/11/07 21:31:13 carl Exp carl $')
OSTYPE(sunos4.1)dnl
DOMAIN(test)dnl
define(`confTRUSTED_USERS', `test')dnl
define(`ALIAS_FILE', `/etc/mail/aliases')dnl
define(`QUEUE_DIR', `/usr/spool/mqueue')dnl
define(`STATUS_FILE', `/etc/mail/sendmail.st')dnl
define(`confCW_FILE', `/etc/mail/sendmail.cw')dnl
define(`confCT_FILE', `/etc/mail/sendmail.ct')dnl
FEATURE(virtusertable, dbm /etc/mail/virtusertable)dnl
FEATURE(relay_entire_domain)dnl
MAILER(local)dnl
MAILER(smtp)dnl
Has anyone else seen this behaviour before? It's a SunOS 4.1.4
machine running resolv+2.11 for DNS in libc, and it appears to
work just fine for everything else. I can't find anything
in the FAQ about it, nor on Claus's webpages (but I may have
missed something).
