sendmail or dns I'm not sure

[David Johnson_5]

Hello,
I am having a problem sending mail from GroupWise to Unix.
My unix server will execpt mail from gwxxx.domain.com, but not gwxxx.mail.domain.com.
And all my mail is from the latter.

Hi,

Put an entry in /etc/mail/access

gwXXX.mail.domain.com RELAY

makemap hash access.db
Then restart sendmail.

Do I need to add the exact address to /etc/mail/acces like guy@mail.domain.com or just mail.domain.com.
because I did the latter and
makemap, stop/start sendmail.
When i sent a message got.
501 Sender domain must exist

[Ross Zubritski]

only XXX.mail.domain.com

Regards,

RZ

ok.
I think the problem is how the unix host sees mail.domain.com. i added the entry in /etc/hosts
###.###.### domain.com mail1 mail 2
only thing is domain.com has 6 aliases for on IP.
It works, but it dosn't seem right.

If you are using /etc/hosts for network resolution you probably don't have a dns issue.

what's in your nsswitch.conf file

Are hosts dns,files

or files,dns

With regards to incoming mail, it should not make a difference. The relay info above should solve the problem.

The /etc/mail/access and access.db didn't seem to do anything.
I did make some chane to /etc/hosts that help some thoug.

Groupwise mailbox are
mailbox1.domain.com
mailbox2.domain.com
mailbox3.domain.com ..etc

dns show the addrees the server
###.###.### domain.com

so i added this to /etc/hosts
###.###.### domain.com mailbox mailbox2 ..etc
seems to work.

below is nssswitch.conf
# /etc/nsswitch.files:
#
# An example file that could be copied over to /etc/nsswitch.conf; it
# does not use any name services.
#
#hosts: dns #files
hosts: files[notfound=continue] dns
passwd: files
group: files
services: files
networks: files
protocols: files
rpc: files
publickey: files
netgroup: files
automount: files
aliases: files
