I have a vaguely similar setup with hundreds of addresses, but it is slightly different. I don't use Dovecot as an lmtp server. I get Postfix to directly write the email to Docevot's mailbox directories. But that does seem uglier than using lmtp. Maybe I should change it, but I like not having to rely on Dovecot for delivery, just in case it's not running for any reason. The other main difference is that I have the large number of address in /etc/postfix/virtual pointing to a small number of entries in /etc/postfix/virtual_mailbox_maps. So the addresses go in virtual, and the accounts go in vmailbox. That seems to me to be a more logical place for the addresses themselves, but it's probably immaterial in practice. cheers, raf
