What 邮箱转移 really involves

邮箱转移 copies messages, folders, rules and the address itself, and only the first of those is automatic. I have moved four mailboxes, and the messages were never the problem. The filters were. Nothing in a 邮箱转移 is as fragile as a rule list.

That is why a migration is a week-long checklist rather than a one-click download. Therefore, plan the order before you touch a single setting. A written 邮箱转移 plan turns a stressful weekend into a checklist.

Key Takeaways

Messages copy themselves over IMAP; folders mostly follow.
Filters, rules and their order need a manual rebuild.
Aliases, forwards and signatures are the items people forget.
Run both mailboxes in parallel for two weeks.
Check the new provider quota before you commit.
A 邮箱转移 that keeps the old address open is the safest version.
Nothing should be deleted until a test message arrives twice.

Four things that travel separately in 邮箱转移

Treat each item below as its own little project, because they fail independently of one another.

Messages

Client-side copying over IMAP is the standard route, and it preserves attachments and dates. Large mailboxes take hours rather than minutes, so start it before a weekend. This is the slowest part of any 邮箱转移, and the only part that cannot be rushed.

Folders and their order

Nesting survives unevenly. Some clients recreate the tree, others flatten it, and a flat tree makes old mail hard to find again.

Filters and rules

Rules almost never migrate. Rebuild them by hand in the same order, because the order is the logic, not the list.

Contacts

Export them as a file first. Auto-complete history does not survive a move, and losing it is the quiet annoyance of 邮箱转移. That small loss is why I now export contacts on day one of every 邮箱转移.

邮箱转移 automatic versus manual work

邮箱转移 and the checklist that prevents loss

Work downwards, not outwards. Checking the destination first avoids the worst outcome, which is discovering a quota limit after half the mail has already copied.

Then add both accounts to one 邮件客户端 and let the first sync run overnight. A single client sees both mailboxes at once, which makes the next three steps far easier to verify. Every 邮箱转移 I have run went smoother with both accounts visible in one place.

Choosing the destination before you move

Compare four things: storage, filter support, alias support and the export options. Storage is the one people check, and alias support is the one they regret ignoring. Two-factor support matters just as much, and 两步验证 is worth enabling before the copy starts.

Additionally, confirm that the new provider allows the connection method your client needs. If you plan to use a desktop app, set the account up there first and let the server do the copying. A provider-side 邮箱转移 is also easier to audit than a manual drag and drop.

邮箱转移 aliases, forwards and signatures

Aliases and 邮件转发 are the hidden half of an address. Twenty aliases pointing at one inbox disappear the moment that inbox is closed, and the sites using them simply start bouncing.

Therefore, write the list down before you move anything. Then decide which aliases need recreating, and which ones are safe to retire, because most people find at least five that nothing still uses. That cleanup is the most valuable by-product of 邮箱转移.

The two-week overlap

Keep both mailboxes live for at least two weeks. Mail that arrives at the old address during that window is the audit trail that tells you what you forgot to update.

Furthermore, set an auto-reply on the old address that names the new one. It costs one line of text and it answers the question before anyone has to ask it.

邮箱转移 when you keep the old address

Sometimes the right answer is not to close anything. If the old address appears on contracts, invoices or a CV, keep it and forward everything instead.

That version of 邮箱转移 is cheaper and reversible, and it removes the recycled-address risk entirely, at the cost of one more inbox to monitor. Many people keep the old address forever, and their 邮箱转移 never really finishes.

Frequently asked questions

How long does 邮箱转移 take?

Plan a week. A realistic 邮箱转移 schedule leaves the manual work for the evenings. The copy itself runs overnight, and the manual parts such as filters, aliases and logins take the rest of the time.

Will my filters move automatically?

Rarely. Some clients can import rules, but the order is often lost, and a rule that runs in the wrong position is worse than no rule.

Can I migrate only part of a mailbox?

Yes, and for most people that is the better plan. Move the last twelve months, then keep the old account readable for anything older. Everything beyond that belongs in a local 邮件归档 export.

What should I do with the old account afterwards?

Forward for a month, verify two test messages, then decide. Closing it too early is the most common mistake in 邮箱转移.
