forwarding email to earthlink...no threads help! 1

[bmcgrathPIX]

OK...i have looked high and low but nothing seems to work. I have exchange 2003, and i want to forward email that comes into a users box to an earthlink address...permenantly. I doubt a rule in outlook will do, as he picks up mail from the road without outlook via earthlink.
i need to set up exchange to forward all mail, internal and external to the earthlink address. i have done this so far...

set up a contact with the earthlink address in this users OU, and forwarded to this contact. (i get a "mail was delayed " error and the messages never get to the user.

i dont know if i need to set up a rule or what.

I need this in a hurry because the user is getting mad!


ahhh!

thanks in advance.

I am having a problem with Eathlink period, my users can't email to their server. I'm getting the delayed message and then finally this error: EarthLink does not recognize your computer (xxx.xxx.xxx.xxx) as connecting from an EarthLink connection. If this is in error, please contact technical support.>

I wonder if its the same thing your getting. Otherwise the exchange server is working great.

In the default SMTP server properties, click the delivery tab, then click the advanced button in the bottom right corner. in the bottom next to "configure external dns server", hit the configure button, and add the ip addresses of your ISP's pri and sec dns servers (such as 4.2.2.1 for verizon, etc).

hope that helps, as i had the same issue...this fixed it.

The post from bmcgrathPIX seems to be the resolution to this message that we were getting when we tried to email anyone at earthlink.net:

There was a SMTP communication problem with the
recipient's email server. Please contact your system administrator.
<our_server.com #5.5.0 smtp;550-EarthLink does not recognize your computer (xxx.xxx.xxx.xxx) as connecting from an EarthLink connection. If this is in error, please contact technical support.>

Earthlink Tech support responded with the following canned message:

Hello,
The information below is of a technical nature and you may wish to forward
this to your mail server administrator in the event that you do not fulfill
that role yourself.
The following error message:

550-EarthLink does not recognize your computer ([IP]) as connecting
from an EarthLink connection. If this is in error, please contact
technical support. or 5.5.0 Relaying Denied

..is due to an improper MTA configuration with the host that is
responsible for delivering outbound mail on your network. In a nutshell,
the mail server which attempted to deliver mail to the earthlink.net e-mail
address was initially unable to successfully deliver the mail to the
earthlink.net MX (more than likely due to high load on our end, no
Earthlink MX host was available to accept the transaction at the moment of
the delivery attempt), and so the Earthlink A record was attempted by
the sending mail server. The earthlink.net A record, however, forwards
port 25 connections to our outbound SMTP servers. Unless the mail server
attempting the transaction maintains IP connectivity through the Earthlink
network, delivery attempts through the A record will consequently fail
and the above quoted error message will be returned.

The behavior exhibited by the sending mail server, in this case, is not
standard. According to RFC 2821, "Address Resolution and Mail Handling":
"If one or more MX RRs are found for a given
name, SMTP systems MUST NOT utilize any A RRs associated with that
name unless they are located using the MX RRs; the "implicit MX" rule
above applies only if there are no MX records present. If MX records
are present, but none of them are usable, this situation MUST be
reported as an error."

http://www.faqs.org/rfcs/rfc2821.html

Currently, the earthlink.net MX records are as follows:

mx4.earthlink.net
mx5.earthlink.net
mx6.earthlink.net
mx7.earthlink.net
mx8.earthlink.net
mx9.earthlink.net
mxa.earthlink.net
mxb.earthlink.net
mxc.earthlink.net
mx1.earthlink.net
mx2.earthlink.net
mx3.earthlink.net

You may wish to verify that you are able to successfully resolve this
record through your name servers, and that you can successfully route
to these hosts.

It has been reported that some Windows-based mail servers behind
firewalls which do not allow transfer of UDP packets larger than 512
bytes may not be able to return the MX record for earthlink.net. For
more information, please see:

http://support.microsoft.com/default.aspx?scid=kb;en-us;828263

However, the byte size of our MX record is under the 512 byte limit and
is within an RFC compliant range. If your firewall restricts UDP packet
transfers though, you may want to verify that it will allow transfer of
a MX record within the size limitations specified by RFC1035:

http://www.faqs.org/rfcs/rfc1035.html

Assuming that the earthlink.net MX is resolvable, if the sending mail
server cannot immediately establish a connection to deliver the intended
e-mail, the MTA should attempt to retry a connection to the Earthlink
MX, rather than defaulting to the earthlink.net A record.

Anyway, just wanted to thank bmcgrathPIX for his reply. It seems like my mail is getting out to Earthlink now.
