Re: Postfix 20010228 on OpenBSD 2.9 could loose mail ?
In recent Postfix snapshots, the trigger client will connect()
write() then wait before close().
The problem that you are referring to just screws up the flush
service, but does not result in lost mail.
If am depressed by gratuitous changes in socket semantics from
"graceful close" (do not lose data that the other side hasn't
received yet) into "ungraceful close".
