[Bug 887599] [NEW] unable to configure or uninstall dovecot-postfix

[Phillip Susi]

Public bug reported:

I installed dovecot-postfix, and it failed to configure.  The same error
apparently prevents it from being removed as well, so now I'm stuck with
a broken package.  The error is:

newaliases: warning: valid_hostname: invalid character 40(decimal): devserv.(null)
newaliases: fatal: file /etc/postfix/main.cf: parameter myhostname: bad parameter value: devserv.(null)
dpkg: error processing postfix (--configure):

This appears to be because my /etc/hosts file listed the FQDN as
"devserv.(null)".  I have corrected the name but the dpkg scripts still
are using the broken name and failing to do anything, even remove
--purge.
