I've just picked up a duplicate of this. Both this and the other bug involve hostnames involving comcast.net. I suspect that Comcast's DHCP service is resulting in these hostnames.
If this is true, then either: 1) A dot terminating a hostname should be disallowed, and the DHCP client should remove a terminating dot from a DHCP response before applying it to the hostname, or 2) The postfix package should remove any terminating dot before supplying a hostname automatically. Note that the other duplicate (bug 629685) is slightly different - it is invalid for a different reason. Workaround: configure the Postfix hostname using /etc/mailname as Clint describes in comment #2. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/625023 Title: invalid myhostname parameter allowed during configuration To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/postfix/+bug/625023/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
