I have Plesk license with unlimited domains, but the following error is received in panel when trying to create a domain:
The maximum number of domains allowed has been reached. (Error code 1)
Error: Unable to update domain data: Failed mail post-configuration: Can't create mail domain servie: mail_Facade->createDomain() failed: mailmng failed: Can't create domain. Domain: example.com [example.com]. Reason: Failed to create 'example.com'. The maximum number of domains allowed has been reached. at (SmarterMail::SMDomain::throwDomainError line 630) at execute console command --add-domain(vconsoleapp::start line 132) at execute "C:\\Program Files (x86)\\Parallels\\Plesk\\/admin/bin/mailmng" --add-domain "--domain-name=example.com" "--total-disk-quota=-1"(vconsoleapp::run line 143)
The SmarterMail license is not installed or inactive.
Go to the Smartermail web login and make sure that the SmarterMail license is installed, and mail accounts' limit has not been reached.
