Plus-addressing (chovy+tag@ -> chovy@) is a hard prerequisite for qaaas.dev's packages/mail but was missing from the example, so tagged mail bounces as an unknown recipient until an operator sets it by hand. Add it with a note that it governs DELIVERY only, not login (Mailu auths the exact address; base <name>@ is the single login and already receives all +tagged mail).

deploy/mailu — self-hosted mail for mail.profullstack.com
Mailu (Postfix + Dovecot + Roundcube + rspamd) as a Docker Compose stack,
fronted by the host Caddy. Full setup, DNS, and architecture: docs/mail.md.

|---|---|
docker-compose.yml |
the Mailu services (mail ports on host, HTTP on loopback) |
mailu.env.example |
config template → copy to mailu.env and fill secrets |
refresh-certs.sh |
copy Caddy's mail.$DOMAIN cert into Mailu, reload (timer) |
provision-mailbox.sh |
create a member mailbox / the gateway master user |
mailu.env, certs/, and data/ are gitignored (secrets + state).
Gateway master user
The agentbbs gateway opens any member's mailbox over IMAP with a single secret,
using Dovecot's master user feature (login <name>*<master>). Enable it with
a Dovecot override so Mailu accepts the * separator:
data/overrides/dovecot/auth-master.conf:
auth_master_user_separator = *
passdb {
driver = static
args = nopassword=y
master = yes
result_success = continue
}
Then create the master account and point agentbbs at it:
./provision-mailbox.sh --master "$(openssl rand -hex 16)"
# AGENTBBS_MAIL_MASTER_USER=gateway, AGENTBBS_MAIL_MASTER_PASS=<that secret>
The exact master-passdb wiring varies by Mailu version; verify against your pinned image before relying on it in production. SMTP submission from the gateway uses the trusted local relay (
127.0.0.1:25), not the master user.
