# Per-domain or per-user transport (relay)

## Manage relay manually

With OpenLDAP backend, per-domain transport is set in domain account with attribute `mtaTransport`, per-user transport is set in user account with the same attribute. For example:

    mtaTransport: dovecot

With SQL backends, per-domain transport is set in SQL table `vmail.domain`, column `transport`. For example:

    sql> USE vmail;

    -- Check current transport settings
    sql> SELECT domain,transport from domain LIMIT 10;

    -- Update transport setting for domain 'my_domain.com'
    sql> UPDATE domain SET transport='[new_transport_here]' WHERE domain='my_domain.com';

Per-user transport is set in table `vmail.mailbox`, column `transport`.

Per-user transport has higher priority. If no per-user transport is set for your mail user, per-domain transport will be used.
