Provider accepts Sieve files
Use olrx export or tbrx export, then srtx generate. You do not need ManageSieve credentials.
Check Sieve and ManageSieve support before you sync.
Sieve is the server-side mail-filter language. ManageSieve is the RFC 5804 protocol used to remotely inspect, validate, upload, and activate Sieve scripts.

Provider exposes ManageSieve
Use olrx run, tbrx run, srtx, or msieve to preview and manage scripts remotely.
Not a fit: a provider without Sieve support cannot run Transiever-generated mail rules. Sieve support alone also does not prove that ManageSieve is available.
Known provider context
- mailbox.org and its Open-Xchange rule editor are validated.
- Migadu, Purelymail, and self-hosted Dovecot/Pigeonhole are documented candidates to verify with your account.
Capabilities, TLS requirements, enabled Sieve extensions, quotas, and webmail editor behavior differ by provider. Preview the exact candidate before deployment.
Next step
For mail-client migration, choose classic Outlook rules to Sieve or Thunderbird filters to Sieve. For direct server operations, start with the ManageSieve CLI.
