Bind your QQ / 163 / Gmail / Outlook / business mailbox to Laifaxin for unified multi-account send and receive — IMAP receiving + SMTP sending; usable in Compose / Mass Email / Smart Follow-up. Supports the vast majority of mailboxes (POP3 not supported).
Quick reference for the 16 major personal mailbox providers Laifaxin supports — Gmail / Yahoo / Outlook / iCloud / AOL / Yandex / mail.ru / QQ / NetEase 163 / Sina / Sohu / Ali / China Mobile / China Telecom / Perfect. Check the password type first — 99% of failures come from picking the wrong one. Personal mailboxes are for 1-on-1 follow-up only; for bulk sending use a quality channel.
AOL Mail (@aol.com) is an American veteran email service, now under Yahoo Inc. Complete setup — generate a 16-char App Password to bind to Laifaxin without enabling 2FA (vs Apple/Google requiring 2FA first).
Complete setup for Apple iCloud Mail (@icloud.com / @me.com / @mac.com) — first enable two-factor authentication (2FA), then generate a 16-char App-Specific Password (xxxx-xxxx-xxxx-xxxx format) at the Apple ID site. Paste it into the Laifaxin password field (not your Apple ID main password).
Complete setup for China Mobile 139 Mail (phone number + @139.com) — enable IMAP/SMTP at webmail [Settings → Account & Security] + 'set' a client password (you define it, not system-generated). Paste the client password into the Laifaxin password field (not the login password).
Complete setup for China Telecom 21CN Mail (@21cn.com and 4 other suffixes) — IMAP/SMTP enabled by default; bind directly with your login password, no auth code needed. Covers security risks, server settings for all 5 suffixes, and foreign-trade suitability.
Laifaxin-supported 7 mainstream enterprise mailboxes quick reference — Google Workspace / Zoho / Tencent / NetEase / Alibaba Cloud / 263 / 35. Enterprise mailboxes use your company's own domain — most professional for foreign trade. None of the 7 allows direct login-password use; all require auth code / app-specific password / client security password + first enabling IMAP/SMTP in the admin console. For bulk sending use premium channels to protect your company's domain reputation.
Complete setup for Microsoft personal email (@outlook.com / @hotmail.com / @live.com) — enable two-step verification + generate app password + paste the app password (not your login password) into the Laifaxin password field. SMTP port is special: 587 + STARTTLS (not 465 SSL).
Complete setup for Perfect Mail (3 suffixes: @88.com / @111.com / @email.cn) — enable IMAP/SMTP first, then generate a 16-char 'app password'. Paste it into the Laifaxin password field (not the login password).
Complete setup for Sina personal email (@sina.com / @sina.cn / @2008.sina.com) — turn on IMAP/SMTP service via web [Settings → Client POP/IMAP/SMTP], pass SMS verification to generate a 16-char client auth code, and paste it into the Laifaxin password field (not the login password).
