Sending email between Exchange and Linux inside domain 1

[burntend]

I am having issues sending email from within our Win2K/Exch2K domain to a linx server running sendmail within the same domain.

The sendmail server is listed in DNS, and anyone in our domain can ping and telnet to the box. However when we attempt to send mail to it (sendmail server), we get a NDR from the Exchange stating error #5.4.0 as the reason it cannot deliver the message. Other servers connect to this box without issue, and this box can connect to the Exchnage server to send/relay mail to users in the domain. What am I missing here?

When we check the logs on the Linux box, there are no attempted connections from the Exch2K server on any port.

Our standard email address is "user@mycompany.com" and the Exc2K server is "host.mycompany.com". The address for the sendmail server is "user@host.mycompany.com".

Thanks in advance,

Burntend

You need to set up the Exchange Server to relay the mail to the linux box to do this use the following Microsoft article:
Setting Up SMTP Domains for Inbound and Relay E-Mail in Exchange 2000 Server (Q260973) (link to Article

http://support.microsoft.com/default.aspx?scid=kb;EN-US;q260973

)

Hope this helps, Thank you,
