Urgent Postfix Problem

[xilus]

All of the sudden postfix no longer works corrrectly.
it starts just fine with /etc/init.d/postfix start

but it logs this error whenever somebody tries to connect to smtp

Jun 19 21:03:56 localhost postfix/tlsmgr[3231]: fatal: open database /var/lib/postfix/smtpd_scache.db: Invalid argument
Jun 19 21:03:57 localhost postfix/master[3225]: warning: process /usr/lib/postfix/tlsmgr pid 3231 exit status 1
Jun 19 21:03:57 localhost postfix/master[3225]: warning: /usr/lib/postfix/tlsmgr: bad command startup -- throttling

I have been adjusting permissions and trying countless things

postfix set-permissions
postfix upgrade-configuration
/etc/init.d/postfix restart

Try this:
- shutdown postfix
- move /var/lib/postfix/smtpd_scache.db to /root/
- start postfix

Seems, that cache file is corrupt.
But instead of deleting, moving seems less intrusiv.

Thank you for your time!
I finally got it by reinstalling postifx and running some wild commands. I what I ended up doing was copying configuration files over from another Ubuntu Distribution.
