This seems like a strange way achieve flexible email addresses. Are you aware of sub-addressing? It has been around for ages, and is supported by Dovecot (and Gmail, incidentally). Imagine an existing email account <al...@example.com>. If alice wants to use a subadress, she signs up with <alice+...@example.com>, and Dovecot can automatically place incoming mail for that address into INBOX/foo (or just INBOX if INBOX/foo does not exist). Alice can use as many sub-adresses as she needs without anybody making config changes. Frankly, the Sieve-based approach you describe seems pretty complicated in comparison. -Ralph
