Hi,

I have set up a postfix server to relay incoming mail to our site.
Depending upon the domain name of the recipient the mail should be
relayed to one of three groupware servers.

First, though, all incoming mail to postfix was sent to one groupware
server, which passed the e-mail onto the other groupware servers. All
went ok.

My transport file looked like this:
domain1.com smtp:[groupware-server1.com]
domain2.com smtp:[groupware-server1.com]
domain3.com smtp:[groupware-server1.com]

All three domainX.com were in relay_domains.
I used /etc/hosts to set the IP address of the groupware-server1.com

I then added in another groupware server (groupware-server2.com) into
/etc/hosts and into the transport file. I used "postmap transport" and
"postfix reload" to update the files and postfix.

my Transport file was:
domain1.com smtp:[groupware-server1.com]
domain2.com smtp:[groupware-server1com]
domain3.com smtp:[groupware-server2.com]
#(domain3.com has been changed)

I can ping groupware-server2.com and the correct IP address is seen
but...when I try to send e-mail I get the reponse in the maillog:

"bashme postfix/smtp[1122]: B6B7B2031E: to=<adriandomain3.com>,
relay=none, delay=0, status=bounced (Name service error for
groupware-server2.com: Host not found)"

I do not understand why I can ping the groupware-server2.com but
postfix cannot send mail there.

any help is appreciated.
