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: yahoo.com slow: 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. ------------------------------------------------------ Mailman-Users mailing list Mailman-Users@python.org http://mail.python.org/mailman/listinfo/mailman-users Mailman FAQ: http://wiki.list.org/x/AgA3 Searchable Archives: http://www.mail-archive.com/mailman-users%40python.org/ Unsubscribe: http://mail.python.org/mailman/options/mailman-users/archive%40jab.org Security Policy: http://wiki.list.org/x/QIA9
