It is transient, but they are blocks and are not retried. Weird,
right?
That's something to talk to your ESP about. They're in charge of
retrying.
in this case esp is sendgrid, with will not as i see it accept msg if
google tempfails it ? :=)
in postfix its proxy content filter, that is not the problem of
tempfails for the sender to sendgrid, same will happend if i stop fuglu
here
or it could simple be sendgrid validate recipients but never succed with
it on google ?
time to wake up for sendgrid :)
