some trouble after changing domainname

[kheno]

1. zmprov gs `zmhostname` | grep oldhostname
zimbraSSLPrivateKey: # name olddomainname.tld
zimbraSshPublicKey: ssh-dss AAAAB3NzaC1kc.....dnyZA== olddomainname.tld

Certs which are installed are for the newdomeinname.tld
What is the best way t change these hostnames without having the need to do do the certinstall again?

2. zmprov mcf zimbraAmavisQuarantineAccount virus-quarantine.hklqsnbrf@newdomeinname.tld
zmprov mcf zimbraSpamIsSpamAccount spam.ouqjkc27p5@newdomeinname.tld
zmprov mcf zimbraSpamIsNotSpamAccount ham.qmhcplmu9@newdomeinname.tld

Those were set to the new domain name. But accounts were not altered. In admin console, old acount were still showing up.

I've tried following with spam/ham
delete and create spam/ham account and then set the attr by zmprv mcf ...
=> retention could not be set to 7 days( though originally it was 7 days)
=> possible other settings? quota, ...?
=> these accounts are now normal user accounts and not system accounts anymore (see icon in the admin console)

I also tried renaming the existing virus-quar account
=> went better, only the retention could not be set to 7 days (cannot be set to less than 30 days)

I've been searching all-around for these. I'm new and still learning. Is there a way of getting all the attributes available for example zmprov md? because zmprov md --help or zmprov help md does not work?

Anyway thanks in advance.
