exclude an IP address from RBL check

[thewolf]

Hi all,

Is there a simple way to exclude an IP address from the RBL check with Plesk for Linux (other than running your own DNS RBL white list)?

Apparently you can do it with tcpserver and tcprules:

But Plesk doesn't seem to use them, it seems to use xinetd instead.

Thanks.

You can edit the /etc/xinetd.d/smtp_psa file and add -a <ip> to exclude the IPs which you dont want to be blocked by the RBL lists:
e.g:
server_args = -Rt0 /usr/sbin/rblsmtpd -a 59.93.244.0 -r relays.ordb.org ..

Hi,

Are you sure that will work?

Here is an excerpt from the rblsmtpd documentation:
http://cr.yp.to/ucspi-tcp/rblsmtpd.html

* -r base: Use base as an RBL source. An IP address a.b.c.d is listed by that source if d.c.b.a.base has a TXT record. rblsmtpd uses the contents of the TXT record as an error message for the client.
* -a base: Use base as an anti-RBL source. An IP address a.b.c.d is anti-listed by that source if d.c.b.a.base has an A record. In this case rblsmtpd does not block mail.

Apparently both the -r and -a options require a DNS server, not the sender IP address.

Thanks.

Hi,

Probably my earlier mentioned option will not work as expected as per your suggestion.
To setup an anti RBL list, we need to install rbldns
from the dnsjbl package. I have not yet implemented this but will post an update on it soon.

Thanks,

Worked for me. My ip at work (day job) was blocking me from sending emails from work. After reading the above suggestion, I added the " -a " option and viola! Emails send without a problem.

Thanks
