I have defined: virtual_alias_maps = hash:/etc/postfix/virtual
virtual_mailbox_domains = my.virtual.domain (sanitized) virtual_mailbox_maps = hash:/etc/postfix/vmailbox virtual_transport = lmtp:unix:private/dovecot-lmtp I'm still testing/configuring locally, so I haven't created the DNS MX record for my.virtual.domain yet. When a client submits a message to a mailbox in that domain (user@my.virtual.domain), I get the following in /var/log/mail.log Jun 30 20:12:31 myhost postfix/submission/smtpd[28379]: warning: Unable to look up MX host for my.virtual.domain: Host not found, try again Why is this happening? In other words, with virtual_mailbox_domains defined, doesn't Postfix know that it is responsible for handling that domain? And, if so, then why is it trying to find an MX? Is there a way to tell Postfix not to bother looking for an MX? Thanks, Michael
