Hi all,
I am familiar with yahoo being difficult to send email to, as i'm sure
most all of us here are. I am now faced with needing to increase my
server's throughput to yahoo's MTA's. I was scouring the net and what
caught my attention on the postfix mailing list archives was a reply
from *Victor Duchovni*
http://tech.groups.yahoo.com/group/postfix-users/message/244843?threaded=1&p=3
I am trying to figure out how to plugin my values to get the equation
correct so I could calculate the what maximal throughput per unit of
concurrency msgs/sec? It seems like I am only sending roughly 800 -
1,000 emails an hour to yahoo. Settings for my yahoo transport are
yahoo_destination_concurrency_limit = 20
yahoo_destination_rate_delay = 1s
yahoo_destination_recipient_limit = 20
I found this cool one liner thanks to Victor
$ perl -lne '
m{\A\S+T(\S+).{5} \S+ \S+: \w+: to=<\S+\@yahoo\.com>, (?:orig_to=\S+,
)?relay=\S+, (?:conn_use=\d+, )?delay=\S+,
delays=[\d.]+/[\d.]+/([\d.]+)/([\d.])+,} or next;
$c = 0.95 * $c + 0.05 * $2;
$d = 0.95 * $d + 0.05 * $3;
if (++$i % 100 == 0) {
printf "%s %5.2f %5.2f\n", $1, $c, $d;
}' maillog

Can anyone offer any guidance on what direction I need to go?
Thanks in advance,
Joey
