Failed to modify server : Missing or invalid mail username prefix

When creating a virutal server with a custom administration username that contains an underscore (for example example_user) the new virutal server is created without any problems. But editing the server after creation will result in "Failed to modify server : Missing or invalid mail username prefix". Apparently the "Mailbox name suffix" can't contain an underscore.

Thanks for pointing this out - it will be fixed in the next Virtualmin release.

That said, I wouldn't recommend creating a domain with an _ in the name for real internet use, as it isn't really allowed in DNS.
