postfix is already the newest version.
The following packages were automatically installed and are no longer required:
  libaprutil1-dbd-sqlite3 libcap2 apache2.2-bin libapr1 libaprutil1-ldap libaprutil1 php5-common
Use 'apt-get autoremove' to remove them.

Setting up postfix (2.7.0-1) ...

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: 202002
newaliases: fatal: file /etc/postfix/main.cf: parameter myhostname: bad parameter value: 202002
dpkg: error processing postfix (--configure):

即使我重新启动，也会出现相同的错误。谢谢您的帮助..

它清楚地指出错误在/etc/postfix/main.cf 中。打开它并修复myhostname值以匹配hostname命令。然后运行service postfix reload并检查它是如何的。
