<DIV></DIV>
<DIV dir=ltr>rfc5321 section 5 indicates that Sendmail <I>should</I> try the
server(s) to whom the alternative MX records point. It shouldn't try all
multihomed A records pointed to by a single MX record (although, that's not
exactly what the RFC says) but that's not the case here. So the question still
is, why doesn't Sendmail try the alternative MX records?<BR>

<DIV>hi</DIV>
<DIV> </DIV>
<DIV>its a bit OT but I hope its OK anyway. We are also using Mailscanner as
outbound scanner and see a problem that I cannot figure out - probably some
setting im missing. </DIV>
<DIV> </DIV>
<DIV>sometimes "we" send emails to a domain where the primary MX record does
not resolve. I would have expected that sendmail would just try the next but
instead it resolves to <A href="http://mxrecord.name.OURDOMAIN.COM"
target=_blank>mxrecord.name.OURDOMAIN.COM</A> (I think) - it seams it
appends our domain and then tries this server and this server says "no
thanks" so the delivery fails. </DIV>
<DIV> </DIV>
<DIV>I tried to lookup the MX myself using the same nameserver as the
mailscanner server is using - this fails so its not the DNS server that
appends something to make it resolveable or gives out a standard IP. </DIV>
<DIV> </DIV>
<DIV>I also checked the resolve file to check that there is not search
setting that would make it search our domain for a valid IP/lookup. </DIV>
<DIV> </DIV>
<DIV>how can I stop this behavior and make it try the next MX in line?
</DIV>
