Spam or phishing emails sent to users' mailboxes through foreign domains can basically be blocked by Alibaba antivirus and Anti-spam gateways. However, because users' accounts and passwords are stolen, the criminals send phishing emails through stolen accounts, which will cause more serious information leakage and property losses.
The main ways for criminals are to crack the user password by hitting the library and to crack the user password by weak password guessing. Then through the obtained account and password, using the SMTP protocol to send spam and phishing emails.
Therefore, how to prevent the leakage of accounts and passwords is the key to eliminate such risks. Alibaba Mail supports two-factor authentication and IP login restrictions. Through these product capabilities, even if the user's account and password are stolen, criminals cannot send spam:
