| Post subject: | Mail to local users bouncing |
Hi, I'm trying to configure Postfix on Centos, but when I send mail to local users, I'm seeing entries like this in /var/log/maillog: Nov 29 06:54:18 li20-189 postfix/smtp[31632]: 1E0C2387AB: to=<localuser@li20-189.localdomain>, orig_to=<localuser>, relay=none, delay=27, delays=27/0.02/0.09/0, dsn=5.4.4, status=bounced (Host or domain name not found. Name service error for name=li20-189.localdomain type=A: Host not found) (the names have been changed to protect the innocent). On my other linode, it's working correctly, and the equivalent log entry is: Nov 29 05:06:07 li16-10 postfix/local[17662]: EB4B486108: to=<localuser@li16-10.members.linode.com>, relay=local, delay=1, status=sent (forwarded as 7526386119) So I'm trying to figure out why one is using li20-189.localdomain while the other is using li16-10.members.linode.com, and where to change it. Any help appreciated. James |

This is a complete stab in the dark, but check the myhostname configuration parameter in your main.cf file. It should be set to your system's FQHN. --James |

That's li20-189.members.linode.com, right? It doesn't seem to be set on the one that's working, but I will try it later. Thanks. |

Hi, The problem seems to have been the myhostname setting, alright. My only problem now is that I can't figure out why the other one works! Thanks for the suggestion, James |

I'm guessing you system's hostname is set correctly on the one which was working and not on the other. Have a look in the docs for your Linux distro to determine how to set it correctly. --James |
