Reputation portability

Receiving providers use signals such as your sending domain and the IP address that sent the message. Comail cannot move provider records to another operator. A new relay uses different IP addresses; their prior history depends on the addresses and provider.

What remains under your control

If you keep the same sending domain and use aligned DKIM with another provider, that provider can sign for your domain. Receiving providers decide how to assess the new mail. Comail cannot promise that a provider will preserve or transfer reputation. See email authentication.

Comail labels are signed records about your DID. The labeler may negate a label when its conditions no longer apply, including when you leave the relay. Do not assume a label will remain active or transfer your relay account or send history. See Atproto labels.

What you rebuild

The IP addresses and sending history belong to the relay. A different provider uses different IP addresses. Their prior history and any warming limits depend on that provider. See Warming tiers.

The operator signature is relay-bound too. comail signs each message with an operator-level domain shared across members. That signature and its feedback-loop routing belong to the relay you sent through, so they do not follow you to a new operator.

Full relay-to-relay migration

Comail does not provide a turnkey way to move a member’s account, suppression state, or relay history to another operator. See Federation for the current limits.
