Postfix Virtual Mailbox Lookup Command: ```bash sudo postmap -q noreply@photosite.vexib.co.uk mysql:/etc/postfix/mysql-virtual-mailbox-maps.cf ``` Result: ```text photosite.vexib.co.uk/noreply/ ``` Status: ```text PASS ``` --- ### 3. Postfix Virtual Alias Lookup Command: ```bash sudo postmap -q info@photosite.vexib.co.uk mysql:/etc/postfix/mysql-virtual-alias-maps.cf ``` Result: ```text blank ``` Explanation: No alias had been created at the time of testing. Status: ```text PASS - no alias expected ``` --- ### 4. Dovecot SQL Authentication Command: ```bash sudo doveadm auth test noreply@photosite.vexib.co.uk ``` Result: ```text passdb: noreply@photosite.vexib.co.uk auth succeeded extra fields: user=noreply@photosite.vexib.co.uk ``` Status: ```text PASS ``` --- ### 5. Inbound Mail Delivery External test message sent to: ```text noreply@photosite.vexib.co.uk ``` Mail log result: ```text dovecot: lmtp(noreply@photosite.vexib.co.uk): saved mail to INBOX postfix/lmtp: to=, relay=mail.vexib.co.uk[private/dovecot-lmtp], dsn=2.0.0, status=sent ``` Status: ```text PASS ``` --- ### 6. IMAP Network Test From client machine: ```bash openssl s_client -connect 192.168.0.39:993 ``` Result included: ```text Verify return code: 0 (ok) * OK [CAPABILITY IMAP4rev1 ... AUTH=PLAIN AUTH=LOGIN] Dovecot (Ubuntu) ready. ``` Additional test: ```bash nc -vz 192.168.0.39 993 ``` Result: ```text Connection to 192.168.0.39 993 port [tcp/imaps] succeeded! ``` Status: ```text PASS ``` --- ### 7. Thunderbird IMAP Login Thunderbird was configured with: ```text Incoming server: mail.vexib.co.uk Port: 993 Security: SSL/TLS Username: noreply@photosite.vexib.co.uk ``` Internal LAN hosts override used: ```text 192.168.0.39 mail.vexib.co.uk ``` Mail log result: ```text dovecot: imap-login: Login: user=, method=PLAIN, rip=192.168.0.43, lip=192.168.0.39, TLS ``` Thunderbird opened the account and displayed the received test email. Status: ```text PASS ``` --- ### 8. Outbound SMTP Delivery A message was sent from: ```text noreply@photosite.vexib.co.uk ``` to: ```text philip.burness@sky.com ``` Result: ```text Message delivered successfully. ``` Status: ```text PASS ``` ## Overall Result ```text Virtual mailbox infrastructure is production-ready for initial Vexib-controlled use. ``` ## Remaining Tests / Future Work The following tests remain useful before wider rollout: ```text Test alias creation and delivery Test albumdb.vexib.co.uk mailbox Test external IMAP login from mobile network / non-LAN network Test mailbox disable behaviour Test domain disable behaviour Test quota behaviour ``` ## Known Issue Internal LAN clients using public DNS for `mail.vexib.co.uk` may fail because of router NAT loopback behaviour. Current workaround: ```text /etc/hosts entry on LAN clients ``` Recommended long-term fix: ```text split DNS / local DNS override ```
