Sorry, that's something I've never seen before. I'm guessing it's a patch to qmail-smtpd, but that's not worth much.

As a short term work-around, you might try adding an entry to the tcp.smtp file for the server in question, with the RELAYCLIENT="" variable set, eg: 70.254.229.27:RELAYCLIENT="",...(plus whatever other variables your server uses typically) This will essentially make your server an open relay for that IP address. I expect this would work, but be careful with it. And don't forget to "qmailctl cdb" after changing the tcp.smtp file.

Here's what I've got in my log file, it's qmail-smtpd doing the rejection.

@400000004e5539281dbe47dc tcpserver: end 10664 status 256

Part of the problem here is that I can't figure out what they've hacked to get
qmail-smtpd to do the rejection. In my /var/qmail/control directory there is
an 'rdns' file with a value of "1"; rdns checking is either on or off.

Any further ideas?  I suppose this may be a lesson for the boss to "install
your own mail server" but that bridge is already crossed. If there's no clear
answer I'll just have to call Inter7 for support and let them deal with it.

That would take care of things if the rejection is due to an RBL, but
the rejection is stated as being due to lack of rDNS, which is
different. The only thing I know of that rejects due to missing rDNS
(using qmail) is spamdyke (a very good anti-spam tool btw).

What specifically is causing the reject? You might post a sample from
your smtp log if you can't tell. If it's spamdyke, then the spamdyke
config has several ways of whitelisting.

Edit your tcp.smtp file and put the address in and set RBLSMTPD="" and it
will bypass the RBL check for that IP address. Afterwards, rebuild your
tcp.smtp.cdb file (depending on how your built your toaster it'll be as
easy as "qmailctl cdb", or some other manual command)

Hope that helps.

Greetings. I hope this list is still intact and that I'm on-topic. I've
searched for a solution and haven't been able to come up with anything.

I've got a problem sprung up recently and can't quite figure out how to
get
around it. While I'm waiting for a bureaucracy to unsnaggle some DNS
information on their side, is there anyway for us to whitelist a single
mail
server that's being rejected for not having rDNS? The mail server is
known to
us and I feel comfortable with taking this action. Hopefully this won't
be a
permanent solution but just a dirty hack while I wait for others to do
their
jobs.

We've got a vanilla Inter7 installed vpopmail/qmail system and I have
not been
able to figure out of this is do-able or not. If it's possible how can I
go
about doing so?

Thanks for any help or pointers.
