Notice that for email (SMTP) to work, the DNS server (the one used by the "senders" side) must have a "MX" entry form your domaain name. Your "hosts" file is not involved.
Thanks for your reply.
This is the case. Right now I have a Red Hat 6.0 box which is accepting this and all email with the same machinename.domainname that I am trying to get working on the SuSE box. I bring that machine down when I am trying to configure the new SuSE box and back up again in a few hours. Mail is flowing fine to that system. My IP provider has a "MX" entry for machinename.domainname with the correct IP. As I said both the SuSE box and the working Red Hat 6.0 system are the same in that respect. This is why I questioned the former statement that I needed a FQDN in my HOSTNAME and /etc/hosts file unless there is something different about SuSE.
Then it is not a dns problem, and it shouldn't be a hosts file either.
I am currently thinking this is an entry of the domain name in some postfix config file. That is assuming the port is set up correctly (see original question in thread). Can anyone help me here?
Instead of:
libros:~ # telnet localhost 25 Trying 127.0.0.1... Connected to localhost. Escape character is '^]'. 220 libros.andante.mn.org ESMTP Postfix
Try to do it giving the same domain name you use for email - then it should try to connect using the eth0 ip address instead of the 127... one. Even better, try from some other machine. You should have a look at these entries in "/etc/sysconfig/postfix" ## Type: string ## Default: "" # # Comma separated list of host-/domainnames for which postfix # should accept mail for. # localhost and the own hostname is appended automatically # POSTFIX_LOCALDOMAINS="" and then run suseconfig. There is also a setting you can use for increased verbosity when debuging: POSTFIX_ADD_debug_peer_list="someserver.somedomain" where that "someserver" would be the one email is coming from. -- Saludos Carlos Robinson
