Hello everyone, I have a mailing list that has 1100 members. Out of those, 177 have Yahoo addresses. Delivery to these Yahoo addresses always delay - even for a whole day. The defer msg from Yahoo is https://help.yahoo.com/kb/postmaster/SLN3434.html In my Exim MTA, I have a special transport for delivering to Yahoo: throttled_smtp: driver = smtp connection_max_messages = 5 max_rcpt = 5 serialize_hosts = * retry_use_local_part hosts_avoid_pipelining = * Yet, Yahoo still doesn't play nice. Now I have opted to have a special retry rule, crafted according to Yahoo's own recommendation from the above page, that we should retry after 4 hours: \N^[^@]+@yahoo.\N * F,4d,5h; ..but this still doesn't sit well with me. Waiting for 4 hours to receive an e-mail just because Yahoo is anal about spam is simply autrajius. The sender domain in question is very DMARC compliant. I have followed https://help.yahoo.com/kb/postmaster/recommended-guidelines-bulk-mail-senders-postmasters-sln3435.html and I believe my server meets everything they want. What other tricks still exist that I haven't explored?? Is there a way to get Yahoo to whitelist a domain+IP ?? Just for the record, I have just signed up with Yahoo feedback loop: https://help.yahoo.com/kb/SLN3438.html so waiting for their approval, if that will help me know who is voting the ML mail as spam. leading to the 421. One more thing - though unrelated. Why are the admins are NOT of keeping the web certificate for the archives up to date? I thought it's trivial with all Unix variants. -- Best regards, Odhiambo WASHINGTON, Nairobi,KE +254 7 3200 0004/+254 7 2274 3223 "Oh, the cruft.", grep ^[^#] :-)
