Hi list,
From me a question that seems to be asked now and then here, but I
could
not find any answers even on whether this is possible in the first
place.
I would like to be able to prioritise outgoing e-mail so they do not
get
stuck in the queue. This as I now and then send out a large number of
e-mails with attachments, and that saturates my connection for a
prolonged
time. It doesn't matter that those mails get out slower, as long as
they
get out eventually I'm happy.
Use a custom transport for these messages with a low concurrency limit,
You mean like installing sendmail or so in parallel to postfix and then
have sendmail send out the lower-priority mails?
or use traffic shaping in the TCP stack to limit the bandwidth per
SMTP connection.
And how would that get certain mails out with priority? It sounds to me
like this would slow down the overall process. I have up to 100 smtp
processes running at a time, but as long as new mails end up at the
back of the queue still no progress there. They have to come first.
Wouter.
