Would it help if there were different cleanup_server parameter
|
||||
names for different message paths? smtpd(8) uses the same
|
||||
cleanup_server value for receiving remote mail and for
|
||||
sending postmaster problem reports. Do we need separate
|
||||
mumble_cleanup_service_name parameters for "inject", "notify"
|
||||
and "forward" (with backwards compatinble defaults)?

Consistency: in postconf.proto make <dt>..</dt> tags bold.

|

According to a paper by Ted Unangst at BSDCON09, kqueue
|
||||
reports state changes, i.e. kqueue indicates when the socket
|
||||
becomes readable. Specifically, he writes when kqueue reports
|
||||
a socket becomes readable but no data is read from that
|
||||
socket, later kqueue calls won't report the socket as
|
||||
readable. That's not what happens on FreeBSD 8.0, where
|
||||
kqueue will keep reporting the socket as readable when
|
||||
nothing is read. Also, FreeBSD 8.0 kqueue still reports
|
||||
the socket as readable after a read operation does not empty
|
||||
the kernel buffer. We need a test program for this that
|
||||
repeats these tests with OpenBSD and NetBSD (and MacOS X
|
||||
once they fix their kqueue implementation).
|
||||
|
||||
postscreen(8): need some option to wait for DNSBL lookup
|
||||
(etc.) completion. For example, postscreen_greet_wait would
|
||||
become a lower bound, while postscreen_dnsbl_wait would
|
||||
become an upper bound (or should all features use a shared
|
||||
postscreen_max_wait upper bound?).
|
||||
|
||||
Would it help if there were different cleanup_service

parameter names for different message paths? smtpd(8) uses

the same cleanup_service value for receiving remote mail
