[Mailman-Users] OT: Yahoo Deferrals

I have a question regarding Yahoo deferrals. I know this subject has
been talked about a lot. Everything I could find via Google was from at
least a year ago though. I was wondering if anybody has found new ways
of limiting the Yahoo deferrals? I run two mailing lists. Each one is
an announcement only list which I send one message to each week. One
list is about 12,000 users and the other is about 9,000 users. I have
noticed that a majority of the e-mail addresses are from yahoo.com so I
get a lot of the deferral messages and it takes a little while to get
them all sent out. Here is what I have done so far.
I am running Mailman version 2.1.12. I have full personalization turned
on to help with bounces. I have all of the verp options turned on:
VERP_CONFIRMATIONS = Yes
VERP_PROBES = Yes
VERP_PERSONALIZED_DELIVERIES = Yes
Everything on the mailman side is working pretty well.
I am running Postfix 2.6.3. I have the following configuration settings
in my main.cf file:
slow_destination_recipient_limit = 5
slow_destination_concurrency_limit = 2
slow_destination_concurrency_failed_cohort_limit = 4
In my transport file I have:
And in my master.cf file I have:
slow unix - - n - - smtp
Is there anything else I can do to help limit the deferrals? I sent an
e-mail to both lists yesterday and it took about 16 hours to get all of
the yahoo.com e-mails out. I guess that is not terrible, but I would
really prefer it to be better.
Thanks for any help or guidance you can give me.
