Bug 52686 – Postfix configuration does not work on system with certain hostnames?

• Status: RESOLVED WORKSFORME
• Product: [OLD] Docs-user

[Description M. Creidieki Crouch 2004-06-01 07:26:51 UTC]

Hi. I'm having problems getting the Postfix installation instructions in the Desktop Installation Guide (URL above) to work. I believe this is because of the way that the hostname, etc. are set up on my system.

I have my hostname and dnsdomainname set up as described in the Gentoo Linux Handbook (http://www.gentoo.org/doc/en/handbook/handbook-x86.xml?part=1&chap=8):
"
#####] cat /etc/hostname
Malakai
#####] cat /etc/dnsdomainname
creidieki
"

I emerge'd postfix as described in the Desktop Configuration Guide (http://www.gentoo.org/doc/en/desktop.xml):
"
#####] emerge -pv postfix
 
These are the packages that I would merge, in order:
 
Calculating dependencies ...done!
[ebuild   R   ] mail-mta/postfix-2.0.19  -ipv6 -ldap -maildir -mbox -mysql +pam -postgres -sasl +ssl  321 kB
"

I then installed postfix, as the guide instructs, but it didn't work on my system. I started without making the configuration changes recommended:

{immediately after emerge'ing}
"
#####] postfix check

postsuper: warning: My hostname Malakai is not a fully qualified name - set myhostname or mydomain in /etc/postfix/main.cf

postfix/postfix-script: starting the Postfix mail system
#####] mutt -x root
#####] mutt -x [e-mail]
"

Neither of the two emails were sent, either locally or remotely. I then changed the /etc/postfix/main.cf file, as described in Code Listing 6.2, and tried again, but this didn't seem to fix the problem:

"
#####] nano -w /etc/postfix/main.cf
#####] postfix stop
postfix: warning: My hostname Malakai is not a fully qualified name - set myhostname or mydomain in /etc/postfix/main.cf
postfix/postfix-script: warning: My hostname Malakai is not a fully qualified name - set myhostname or mydomain in /etc/postfix/main.cf
postfix/postfix-script: stopping the Postfix mail system
#####] postfix check

postsuper: warning: My hostname Malakai is not a fully qualified name - set myhostname or mydomain in /etc/postfix/main.cf
"

I am using DHCP to connect to the internet. The output of "emerge info" follows:

Have you tried something like this in your /etc/hosts ?
127.0.0.1     your_host_name.localhost.localdomain     your_host_name

[Comment 2 M. Creidieki Crouch 2004-06-03 05:22:06 UTC]

Lang,

That makes the error messages go away, but my mail still isn't able to get to outside hosts. I have my hostname set to "Malakai", because it sounds neat, but I don't actually have "malakai.dsl.telerama.com" from my ISP, I have something that DHCP gives me ("dsl-nnn-nnn.dsl.telerama.com"). This can change based on the IP address that I get from DHCP. I know I can't receive mail reliably at a changing email address, but can I set postfix up so that I can send mail without it getting bounced?

IMHO, it is might just a mis config. I suggest you post your qustion in here: http://forums.gentoo.org/viewforum.php?f=18 . It is easier to help you that way. When you get everything straighten out, come back and state what need to be change in the doc.
