Panel Backend
v1.0.541
Mail hostname no longer falls back to a branded .local placeholder.
Improvements
2- Mail hostname derivation now first prefers the machine OS FQDN when the panel hostname is a bare IP, recovering a correct mail.<your-domain> identity automatically with zero admin action.
- When no real domain can be recovered, the mail hostname falls back to the neutral, non-branded localhost.localdomain (Postfix compiled default) instead of a Panelica-branded name.
Bug Fixes
2- SH-115: When no real domain is available for a server (bare-IP hostname), Postfix mail identity (myhostname/mydomain) no longer defaults to the branded mail.panelica.local / panelica.local placeholder. The .local suffix is RFC 6762 mDNS-reserved with no public A record, so DNS and deliverability checks were flagging mail servers as non-existent.
- This is a self-healing fix: existing installs correct themselves automatically on the next backend startup or hostname change, no manual action required.
