B.com's ip is 61.*.*.11. I try to send email from A to B. and I get
the maillog below:

Jan 24 10:28:25 localhost sendmail[10927]: l0O246dv010298:
to=<ming@B.com>, ctladdr=<ming@A.com> (500/500),
delay=00:24:19, xdelay=00:00:00, mailer=esmtp, pri=570314,
relay=61.*.*.11. [221.*.*.35], dsn=4.0.0, stat=Deferred: Connection
refused by 61.*.*.11.

as you see, there is another ip 221.*.*.35 in the maillog, why is it
there?

'*' is not a legal character in a domain name and is never part of an IP
address. The domain names a.com and b.com are both reserved by
IANA, and have no resolution at all.

You won't be able to get much useful if you insist on hiding the
critical facts to answer your question.

thanks. but i dont think it critical, they are just 2 common IPs. What
I wonder is why 221.*.*.35 is there.

And if you posted real data, we might be able to tell you - now all we
can do is guess. One possible guess is that the MX record for "B.com"
brokenly gives an IP address instead of a host name, and that that IP
address when treated as a host name per the spec, i.e. used in an A
lookup, actually resolves to a different IP address.

When running nslookup, the result is right,both A & MX records.

You are wrong. No one can answer specifically as long as you insist upon
obscuring the critical information to answer your question.

>What
> I wonder is why 221.*.*.35 is there.

I invite you to examine the Sendmail source for your answer. Apply
the actual information that you pointlessly insist on keeping secret and
an understanding of Sendmail and you will get your answer.
