Hi
are there some data which value is acceptable for
"postscreen_greet_wait" to not end in legit SMTP servers give up and
try again later?
Klensin Standards Track [Page 56]
RFC 2821 Simple Mail Transfer Protocol April 2001
An SMTP server SHOULD have a timeout of at least 5 minutes while it
is awaiting the next command from the sender.
Of course, some admins do things differently.
thanks!
well, that's the other direction while in general the question goes more
in the direction of practical expierience of legit
smtp-*client*-timeouts in the wild
given that we have "postscreen_greet_ttl" the impact for legit mail is
low *as long* the sending server don't give up the first time it needs
to pass the tests and with around 3500-5000 legit mail each day there is
no rush at the moment
BTW: mailgraph in the meantime shows a *dramatical* breakdown in
delivery attemts from the moment of the config change
