I have a problem that I'm unable to figure out.
I hope somebody here can help me out.
We have an Exchange 2003 server running on a Win 2000 server and the SMTP
service is giving me problems.
The local domain is company.local, but we receive mail on domain1.com. This
one is added on the Exchange server and works like a charm. It's in the
default recipient policy etc.
Now I'm trying to add domain2.com. That one however does NOT work.
When trying to send to a domain2.com-address I get the "550 5.7.1 Unable to
relay for XXXX@XXXXX.COM "-error.
It's only external, incoming mails that does not work. The mailboxes are
there. The users can log on to them. They can send mail to any addresses.
Internal mail (i.e. from XXXX@XXXXX.COM to XXXX@XXXXX.COM ) works as it
should. OWA works.
The new domain is in the default recipient policy together with the old one.
I've also added a new connector with the new domain and "Allow messages to
be relayed to these domains".
The problem seems to be that the SMTP services does not recognize
domain2.com as an incoming address.
I've tried everything else I can think of; allowing the SMTP service to
relay, verifying that the Exchange server is in the correct user group and
has the correct rights, deleting the keys in the MetaBase etc but nothing
I can't seem to find any info on this since most articles/posts are about
the default recipient policy which seems ok to me.
I have both domain1.com and domain2.com in there, both replicates to AD as
they should and so on.
What really gets to me is that, as far as I can see, there is no difference
between domain1.com and domain2.com except ofcourse for the fact that
domain1.com works and domain2.com does not!
Any help or ideas would be greatly appreciated !!
