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();
    }
}
