Is there a simple elegant solution that can reuse the database content but under a different mapping to allow it to be accepted and forwarded along to the internal mail server? Last time I did something like this it was with Sendmail using LDAP for smart host routing of mailboxes. smime.p7s Description: S/MIME Cryptographic Signature

Looking for pointers to assist me
I've had my Postfix mail server running for several years now using Postfixadmin to manage the database tables holding my virtual mailbox information for domains I'm hosting mail from. It's become time to move this mail server so I'm having to rebuild it and I'm wanting to put the mailboxes behind a firewall but have an SMTP relay host that will accept the mail and forward it in. Obviously I don't want to just blindly accept all email for the domains and relay it into the internal host which would then have to deal with sending back scatter for invalid addresses. My current configuration handled the configuration using virtual_mailbox_maps, virtual_alias_maps and virtual_mailbox_domains settings that were pointed to the configuration files that generated the appropriate queries for the database. Obviously I'll be reusing this for my internal postfix server behind the firewall which will be receiving the emails but I'm trying to determine how to modify for my relay to be able to validate the email before relaying it into the internal host. smime.p7s Description: S/MIME Cryptographic Signature
