Exchange & Solaris 2.6 sendmail

[Cory Powers]

I have a Solaris 2.6 server running sendmail that receives e-mail fine from
most places. It is the only server in the domain darwin.net and its FQDN is
charles.darwin.net.

Our parent company uses Exchange to send e-mail and they can not send to
addresses at darwin.net, e.g. cpo...@darwin.net. But they can send to
addresses at charles.darwin.net, e.g. cpo...@charles.darwin.net.

Most other servers can send to either address except for a couple of
Exchange
servers. Any help would be greatly appreciated.

Please send to the group and my e-mail, cpo...@hsacorp.net.

Thanks

Is there a MX record for darwin.net? Does it point to the rught A
record?

It should work.

Darwin.net is an MX record which points to Charles.darwin.net as the Name of
the server handling the request. Which then in turn shows the IP address for
charles.darwin.net as the A record.

I would suggest enabling the protocol log on the IMS properties to see what
happens when an Exchange server (you will have to know their IP address)
connects to you.

The MX record is the first thing that comes to mind, but I'd be curious what
the error message that the sending party is getting back. Logging of the
IMS, as suggested, is also a good tool.

If that works, does RESTEST resolve the e-mail domain properly?
(RESTEST can be found on the server CD if it's not already installed
in the exchsrvr\bin directory or somewhere else on your disk).
