Thanks for uploading vmmark2initialization template. However, it shows several errors.
Before filling out the vmmark2intialization template, make sure you know
#1 mailserver hostname
#2 mailserver domain name first part
#3 additional 2 parts of the mailserver domain name
I am guessing these values, for you, should be
#1 mailserver0
#2 mail0
#3 mail0.ini
If I saw your VMMARK.CONFIG I would know for sure.
Your fully qualified mailserver hostname is mailserver0.mail0.mail0.ini.
Find and replace each of the strings in your vmmark2initialization template with the corrected ones below:
<ClientAccessServers> <string>mailserver0.mail0.mail0.ini</string><TargetForest>mail0</TargetForest><DirectoryDomain>mail0</DirectoryDomain><MasterDomain>mail0</MasterDomain>
As directed in the default initialization template, TargetForest, DirectoryDomain and MasterDomain need to contain your equivalent of "maildomainN". For you this would be "mail0".
<string> needs to include the fully qualified domain name including the hostname.
Thanks,
Rebecca
