relaying denied



Hi,

I just have a question about the log messages I am receiving. Here's the
explanation of my setup.

We used to have two servers: X and Y. We had Sendmail running only on one
of them (X). Last month we completely wiped everything and changed the
setup of what is running on each server. Now we have Sendmail running on
both servers. Most of the virtual domains/websites that USED to be on X
are NOW on Y. The mail works fine on both servers. Users on Y are
receiving mail perfectly. However, I am getting a LOT of 'relaying denied'
and 'relaying temporarily disabled' on the X server for the domains that
are currently on Y.

I have checked the zone information for each of the domains on Y and they
have MX records listed correctly -- mail should first go to Y, then to X.
             MX   10 Y.ns1.com
             MX   15 X.ns2.com

So my question is: if mail is received on Y why am is it still trying be
relayed though X for the domains that are on Y?

Here's a snippet of my log messages from /var/log/maillog:
Jun 20 04:06:17 sendmail[30589]: i5K968bv030589: ruleset=check_rcpt,
arg1=<valeria zzz net>, relay=[61.51.250.44], reject=550 5.7.1
<valeria zzz net>... Relaying denied. IP name lookup failed [61.51.250.44]
Jun 20 04:06:19 sendmail[30589]: i5K968bv030589: lost input channel from
[61.51.250.44] to MTA after rcpt
Jun 20 04:06:19 sendmail[30589]: i5K968bv030589:
from=<Carolyhcd panda com>, size=0, class=0, nrcpts=0, proto=SMTP,
daemon=MTA, relay=[61.51.250.44]
Jun 20 04:09:39 sendmail[30590]: i5K99b9w030590: ruleset=check_rcpt,
arg1=<webmaster site net>, relay=YahooBB219007126054.bbtec.net
[219.7.126.54], reject=550 5.7.1 <webmaster site net>... Relaying denied.
Proper authentication required.
Jun 20 04:09:39 sendmail[30590]: i5K99b9w030590:  reject=550 5.7.1

And others:
Relaying denied. IP name lookup failed [220.89.226.158]
Relaying denied. IP name possibly forged [65.91.92.64]
Relaying denied. IP name lookup failed [219.248.33.52]


And from the log file sent to root:
Relaying denied:
>From [actual ip address here] to radium mysite net: 1 Times(s)
>From [actual ip address here] to alex mysite net: 1 Times(s)


Anything I can do about those messages? Each day I get about 200 or so of
these in root mail. (I have changed some sensitive info in the examples
that I provided, but the gist of it should be there.)
Thank you.

Olga
