Hi
I have some issue metadata caching as shown below:
The install/update may have failed due to metadata caching issues. Please clean the cache by clicking the button below and retry the install/update operation.
Here is information for my VPS
System version
NethServer release 7.5.1804 (final)
Kernel release
2.6.32-042stab125.5
My Question is, if I buy NethServer Subscription “Crostino Good Starter” the issues fixed ?
Other question if I would like add more three domains for mail server, the Nethserver support multi domain ?
Why when I try to add email account the system not allow choose @domain ?
Getting crostino will help to get the server more reliable after updates. There is no guarantee that it will solve your current issue. But there have been similar problems in the past that could be resolved. I am sure, when digging into the problem, we will fix this issue too.
Yes you can add more domains to the NethServer mail module, BUT, they will always be as aliases for the (probably should use another word for this) primairy mail domain.
See comment above: other addresses with another maildomain will be an alias. Have a read here: Email — NethServer 7 Final
