On my work account, I'm using different identities depending on either I send e-mails or respond on behalf of my team or on my own. In both cases I use different BCC addresses, either to send the response to the team's mail alias, or to ensure that the message is signed with my own GPG key so that I could read it in the future.
At the moment K-9 allows only to specify a global BCC address, but not per-identity BCC address (CC is supported). This forces me to either not sent the e-mails from the phone at all, or to write the BCC address manually each time so that I sent it to the correct mailbox. If the BCC field could be set per-identity, that would make this process easier to use.
