[问题] Help with a sendmail configuration?
We do a lot of virtual hosting..
We do all of our sendmail work on one machine
name : mail
let's say we have a domain
testdomain.com
and we have it on machine : blahbox
and a cgi script tries to send an e-mail to:
blah@testdomain.com
from blahbox
it comes back with a user unknown..
but sending it from anywhere else works fine.
now in testdomain.com
the mx records will look like this :
IN MX 0 mail.iuinc.com.
IN MX 10 relay.iuinc.com.
which are our mail servers..
and the virtualusertable reference for tihs domain would be
@testdomain.com user@hisisp.com
can anybody help me with some ideas here?
[回答1]
Have you added a Cw line to sendmail.cf or alturnativly added the domain
to sendmail.cw?

Yeah we have all of that configured..
Basically the problem is we have one mailhost
and that mailhost does our virtualusertable stuff.
When another machbine, wihch has a domain on it
tries to send to an alias.. it doesnt kno to
go to our mailhost. it just tries to deliver it locally
anyone got an idea?

First of all, make sure this other machine *doesn't* have the domain
listed in sendmail.cw.
Next, you may want to explicitly set this machine up as a relay for the
domain, i.e., add a FEATURE(mailertable...) in the m4 file you use to
generate the .cf file, and make sure you have
testdomain.com relay:mail.yourdomain.com
in your mailertable.
That will insure that mail will be relayed to the correct machine.

hrm I tried doing this.. no luck.
could it matter that this machine has about 60 domains on it?
i setup the mailertable stuff, and make the mailertable (ande used makemap
on it)
and in it
i put
dentronix.com relay:mail.iuinc.com
still when i'm on the machine and try to send mail
to blah@dentronix.com it just says user unknown
any other ideas?
[回答5]
Shouldn't matter at all. If I look at the machine:
[mark@frigg .netscape]$ telnet relay.iuinc.com smtp
Trying 205.147.201.4...
Connected to relay.iuinc.com.
Escape character is '^]'.
220 dsn.iuinc.com ESMTP Sendmail 8.8.5/8.8.5; Wed, 20 May 1998 15:45:54-0400
expn anyone@dentronix.com
250 <anyone@dentronix.com>
looks fine -- not trying to expand the alias.
Did you shutdown sendmail entirely after changing your sendmail.cw file?
You need to make sure that sendmail restarts after any change. Also, did
you correctly build your mailertable database after adding it? I think
sendmail defaults to hash ('though we use btree here).

yeaeh.
i setup the mailertable on pappa (the machine we have the domain on)
as follows :
dentronix.com relay:mail.iuinc.com
and when i try mailing from pappa it dies
[回答7]
By default, sendmail treats as local all domains corresponding to
local IP addresses. To disable this behaviour, enable the option
O DontProbeInterfaces=True
in sendmail.cf. This option only exists in recent version of sendmail
(8.8.5 or later, I believe).

I'm trying it under 8.8.8 and it's telling me :
554 /etc/sendmail.cf: line 446: readcf: unknown option name
DontProbeInterfaces

Sorry, it's new to 8.9.0.
If you don't want to upgrade (and 8.9.0 is quite a significant
upgrade), you'll need to replace all occurrences of $=w with $=v, Cw
with Cv, and Fw with Fv.
