found external domain "chandpurtelecom.xyz" in litespeed admin panel and postfix main.cf and another external domain mail.multipletopup.com in dovecot.conf, which are vulnerable,
and also mail can't provide ssl mail due to wrong config in postfix main.cf 'smtpd_sasl_auth_enable or smtp_tls_security_level',
and don't have mail alias support,
also dont have wildcard and 4096bit ssl, and it generate ssl for only root domain and not for www domain alias
