relayEmail opens a read stream on the .eml file for every relay, and only client.send() ever consumed it. When the auto-relay rules left no recipients, or the outgoing server failed the send (e.g. rejected a recipient), the stream was never read or destroyed and its file descriptor stayed open. Destroy it on the early return and in the finally block; after a successful send it is already fully read, so that is a no-op.

Close the raw `.eml` stream when a relay does not send it (#423). Every relay
|
|
that ended without sending (no recipients left after the auto-relay rules, or
|
|
an error from the outgoing server) kept one file descriptor open, so a
|
|
long-running instance eventually hit the descriptor limit and auto-relay
|
|
stopped working.
