VHCS ->iscCP mess..

[Zeitkind]

Hi,
after checking the progress of ispCP for some months, I finally decided to upgrade.
One reason was a Debian sarge (601 days uptime *sigh* which needed to get updated anyway and the lack of support for VHCS2.

What I had:
A working VHCS2 with some little mods:
VHCS2 did nothing to my bind files, I have ~25 domains running, but prefered to make the host-files & config (eg. slave) by myself. It was simply a "do nothing"-hack to the script. No users added domains by themself, it is a more private server.
postfix config was completly rewritten to add more RBLs, SPF and such.
I did nothing to the "main" VHCS2 things like db-layout etc.

What I did:
- Upgraded sarge AMD64 to etch without much problems. All went fine.
- checked the packages ispCP needed - all fine
- run setup & upgrade script - all fine

Looked quite good. But...
- all sites had a ispcp-login instead of the content
- DNS totally screwd - expected that, I could have fixed this
- no POP or IMAP login was possible at all
- Amavis, spamassassin & policyd screwed and completely broken
The only thing that was running was postfix

I googled around, did not find much help, so I decided to do a "half-clean" install. I purged bind, apache, courier, postfix etc. - all I kept was mySQL. Did a mySQL dump of ispCP-tables, trashed the /etc/<package> dirs and reinstalled the services. Started over with iscCP setup and found an empty db. Imported the ispcp.sql and set all status to toadd. My users and domains came back.. fine.
Noticed that https, pop-ssl, imap-ssl, policy-weight and spamassassin were not running. Seems the debian-packages-etch miss some stuff like courier-ssl, installed them and services were up. Apache-ssl configured simular to the hint here somehwere - fine. Now all services are running, sites show their content again, postfix is running - but..
Still can't login to pop3 or imap.

Sending emails seems to work:

Spamassassin doesn't work too, but I guess it's simply not configured like clamav.
I never dealed with courier before, so I have absolutely no idea where to look at, any hints/suggestions are welcome.
