Re: Will this cause NDR's

Tech-Archive recommends: Speed Up your PC by fixing your registry

Ok, I get that. But why the one send to site and not the others on the same
host?

Hi:

Customer is asking for verification that the following, as shown on their
DNS report, will not cause their mail to be blocked by the recipient
server. Strangely, they control both ends of this arrangement, hosting
their own mail on exchange and sending to several subsidiaries hosted at
Gmail, of all places. But only one is blocked. My take is that if a
universal setting like this would block the mail, it would happen at all
the sub sites hosted at Gmail.

<snip>
WARNING: One or more of your mailservers is claiming to be a host other
than what it really is (the SMTP greeting should be a 3-digit code,
followed by a space or a dash, then the host name). If your mailserver
sends out E-mail using this domain in its EHLO or HELO, your E-mail might
get blocked by anti-spam software. This is also a technical violation of
RFC821 4.3 (and RFC2821 4.3.1). Note that the hostname given in the SMTP
greeting should have an A record pointing back to the same server. Note
that this one test may use a cached DNS record.

mail.customerdomain.com claims to be host customerdomain.com [but that
host is at aaa.bbb.ccc.ddd(may be cached), not www.xxx.yyy.zzz]. <br />
<end snip>

Thanks for your help.

Yes, this will cause some (but not all) of their email to be blocked.
Some organizations do this check before accepting incoming mail.

Lee.
