Fixes Roundcube IMAP "Internal error occurred" caused by Dovecot
running mail processes as uid 102 (Alpine default) instead of the
actual vmail user uid 5000.
Changes:
- configure_postfix: virtual_uid_maps/gid_maps 102/105 → 5000/5000
- configure_dovecot: mail_uid/gid, first_valid_uid, userdb args
- cmd_add_user: passwd file entries and ownership

Ensure /etc/dovecot/users has 644 permissions and root:dovecot ownership
after adding a user. Without this, dovecot cannot read the passwd-file
and authentication fails with "Permission denied".

- Create login/token-login/empty directories with correct ownership
- Set proper permissions for dovenull user on login directories
- Remove stale auth-token-secret.dat on startup (prevents "compromised token" errors)
- Increase sleep time after dovecot start for socket creation
- Fix permissions again after socket creation

Add permission fix for /etc/dovecot/users in startup script.
Without this, dovecot auth fails with "Permission denied" when
trying to read the passwd-file for LMTP delivery.

The firewall-setup command now adds:
- Input rules for ports 25, 143, 465, 587, 993 (accept from WAN)
- Forward rules for mail ports (WAN -> LAN mailserver)
- DNAT rules in firewall.user (excluding LAN subnet)
This ensures nftables input_wan and forward_wan chains allow
mail traffic to reach the mailserver container.

Alpine Linux uses LMDB instead of Berkeley DB hash format.

- nftables input_wan missing port 25 accept rule
- gk2@secubox.in missing from vmailbox

mydestination included $mydomain which caused "User unknown in local
recipient table" errors because Postfix treated the domain as local
instead of virtual.
Changes:
- Remove $mydomain from mydestination in setup.sh
- Update fix-postfix command to also fix this issue
- Ensure vdomains file is properly created

Alpine Linux's Postfix is compiled with LMDB support, not BerkeleyDB
hash support. This caused "Temporary lookup failure" errors on send.
Changes:
- Changed virtual_alias_maps and virtual_mailbox_maps to lmdb: prefix
- Copy resolv.conf to Postfix chroot for DNS resolution
- Added `mailctl fix-postfix` command to repair existing installations
Root cause: virtual_alias_maps was configured as hash:/etc/postfix/virtual
but the hash map type is not supported on Alpine, only lmdb.
