v1.0.548

Patch Rilasciata il 27 settembre 2026

Fix the spam-folder adoption storm seen on the first live 1.0.547 deployment.

Batch mailbox adoption re-rendered the spam filter rule and reloaded Dovecot once per account instead of once at the end, causing 121+19 SIGHUP reloads at boot on a 142-account server; each reload restarted the auth process mid-flight and made the next accounts doveadm call see a transient auth-master Disconnected unexpectedly error. 21 accounts were deferred as a result (no mail was lost); they completed after a backend restart. This release performs the adoption without the reload storm.
doveadm calls now retry (8x, 1s backoff) on that specific transient auth-disconnect error; genuine results (folder exists or missing) are never retried.
