- A @hello.kamocrm.com sender is refused relay here with a 4xx, so bulk mail can only leave through postfix-bulk; delivery to our own domains is unaffected. hello.kamocrm.com is an alias-only domain whose bounces and replies go to postmaster. - Replies to NoReply@KamoCRM.com went to a mailbox that does not exist and bounced; they now reach postmaster. - The TLS session cache was btree, which Alpine's postfix cannot open, so every TLS client paid a full handshake; it is lmdb now. - The alias map was never compiled; newaliases builds it at start.
