Convert classic Outlook rules to server-side Sieve.

olrx exports supported classic Outlook receive rules so that a Sieve-capable mail server can apply them before mail reaches your phone, webmail, or another desktop client.

When to use olrx

You use classic Outlook for Windows and want supported receive rules to work server-side.
Your provider accepts Sieve scripts, or exposes ManageSieve for preview and deployment.
You want a guided preview, server-side backup, and rollback rather than hand-editing scripts.

Not a fit: olrx requires configured classic Outlook for Windows. It does not turn unsupported rules or a provider without Sieve support into compatible server-side rules.

Sync through ManageSieve

Set the connection values for a provider that offers ManageSieve, then run the Outlook workflow. The command shows the result and asks before changing server rules.

TRANSIEVER_SIEVE_HOST=sieve.example.com
TRANSIEVER_SIEVE_USERNAME=user@example.com
TRANSIEVER_SIEVE_PASSWORD=secret

olrx run

ManageSieve is the RFC 5804 protocol for remotely managing Sieve scripts.

Export without ManageSieve

If your provider accepts a Sieve file but does not expose ManageSieve, export the supported Outlook rules locally and generate the Sieve script with srtx.

olrx export --rules outlook-rules.json
srtx generate --rules outlook-rules.json --sieve outlook.sieve

See the olrx repository for supported rule mapping and the provider guide before deployment.
