Question:What settings should I do to automatize new e-mail creating (while creating subdomain it would get a standard e-mail automatically)?

Answer:You should turn on the function of subdomain automatic creation for your main domain on the ISPmanager panel. This function allows to create third-level domains to the main domain automatically, without required configuration changes, exempting you, this way, from additional operations. Subdomain will be created with creating directories in proper catalogues.
