How can I send a copy of all outgoing messages to another mailbox?


The most straightforward way is to set up a system filter, and include a command such as:

unseen deliver mailbox@whatever.domain

This sends a copy of every message to [mailbox@whatever.domain](mailto:mailbox@whatever.domain) (unless the message already has that recipient - Exim never does duplicate deliveries). To save only outgoing messages, you need to come up with a definition of what outgoing means. Typically, this might be a check on the sender address and/or on the originating host. Here is an example:

if $sender_address_domain is mydomain.com and
   ${mask:$sender_host_address/24} is
  unseen deliver mailbox@whatever.domain

Question: Is this outdated in regards to IPv6?
