Subject: "Connection refused" not skipped

We are still running 19990601 here (just in train to upgrade).

Every now and then outgoing SMTP mails are deferred because the first IP
address of
an outside mailserver is not responding (Connection refused) even while the
others
would respond.

E.g. the MX for "4c-ag.de" points to mailin.webmailer.de, and this one has
3 IPs
        Name: mailin.webmailer.de
        Addresses: 192.67.198.48, 192.67.198.37, 192.67.198.32

I found the section on "postfix defers if the first MX responds 4xx or 5xx"
(and does
not try other MXs), but this sounds unrelated.

Is the above setup non-conforming (and just happens to work with other
MTAs),
or do I miss some configuration item which fixes this behavior (why not try
the
other IP addresses)?
