[Bug 429769] Re: package postfix 2.5.5-1.1 failed to install/upgrade: subprocess post-installation script returned error exit status 75

[Bart de Koning]

Same error on my machine.
it looks like postfix cannot handle a hostname that consists of only numbers

sudo dpkg --configure postfix
Instellen van postfix (2.5.5-1.1) ...

Postfix configuration was not changed.  If you need to make changes, edit
/etc/postfix/main.cf (and others) as needed.  To view Postfix configuration
values, see postconf(1).

After modifying main.cf, be sure to run '/etc/init.d/postfix reload'.

Running newaliases
newaliases: warning: valid_hostname: numeric hostname: 0111055
newaliases: fatal: file /etc/postfix/main.cf: parameter myhostname: bad parameter value: 0111055
