This can be solved with the following regex:

"^([^@]+)@([^;]+);([^:]+):(.+)$"

• ^ assert position at the start of the string
  • ([^@]+) capturing group for one or more characters, excluding '@' character (IP)
  • @ match '@' character
  • ([^;]+) capturing group for one or more characters, excluding ';' character (DOMAIN)
  • ; match ';' character
  • ([^:]+) capturing group for one or more characters, excluding ':' character (USERNAME)
  • : match ':' character
  • (.+) capturing group for one or more characters (PASSWORD)
• $ assert position at the end of the string

Regex regex = new Regex("^([^@]+)@([^;]+);([^:]+):(.+)$", RegexOptions.Compiled);

string[] lines = File.ReadAllLines("PathToTheList");
foreach (string line in lines)
{
    Match match = regex.Match(line);
    if (match.Success)
    {
        GroupCollection groups = match.Groups;
        // group[0].ToString() == line
        string ip = groups[1].ToString();
        string domain = groups[2].ToString();
        string username = groups[3].ToString();
        string password = groups[4].ToString();
    }
