 * 1. query Mozilla ISPDB for domain from email (perfering SSL over STARTTLS over insecure connection)
 * 2. guessing and verifying in DNS server-names based on domain from email:
 *	- (imap|smtp).$domain, mail.$domain
 *  - MX is *.mail.protection.outlook.com use (outlook|smtp).office365.com
 *  - MX for $domain
 *  - replace host in MX with (imap|smtp) or mail
